(17.12.12) IXYS Announces Robust Isolated Solid State Relay with Integrated Current Limit, Over-voltage Protection and Thermal Management
The CPC1593 Self-resetting, Triple Protection Scheme Protects Load and Itself
IXYS Integrated Circuits Division (formerly Clare, Inc.), announced the immediate availability of the CPC1593, the first in a new family of triple stage protection solid state relays (SSRs) that incorporate load current-limiting with over-voltage protection and thermal management.These bidirectional relays are designed to survive in the harshest operating environments off-AC line applications.
The CPC1593 normally open (1-Form-A) optically isolated SSR features a load voltage of 600V peak maximum, continuous load current of +/- 120mA maximum and an on-resistance of 35 Ohms maximum. In a fault condition, the CPC1593 relay features a unique over-voltage protection that is activated when the voltage across the switch is greater than 21V and the device is in current limit. The over-voltage protection deactivates the switch while allowing a restricted load current of less than 100uA to flow. When the voltage across the switch falls below the over-voltage threshold, the switch resumes normal operation. If the fault persists, the over-voltage response will repeat offering the best protection for the load and the switch itself.
Current limit specification for the CPC1593 in an AC/DC configuration is +/- 285mA maximum and 570mA in the DC configuration. A thermal management circuit in the CPC1593 monitors overall die temperature in a fault condition and further restricts load current to protect the relay and load.
Key applications for this device are for advanced power management applications where the reduction of “vampire power” consumption is desired by turning off the AC power when not needed. Other applications include in-rush current control, power supplies, industrial and process controllers, solenoid and valve controls and HVAC. The device is targeted for AC power line environments where fault conditions can persist for extended periods of time and where upon removal of the fault, return to normal operation is expected. The relay is designed to survive extended power cross conditions. The CPC1593 has UL, CSA and EN/IEC approval.

320V Bidirectional Switch Capability for High-Voltage Interface Applications Powered by a 3.3V Digital Supply
Clare, Inc. has announced the availability of the CPC7514Z Quad High- Voltage Isolated Analog Switch Array for use in industrial controls, instrumentation, automatic test equipment and telecom applications. The CPC7514Z ICs feature four independently controlled, 320V bidirectional normally open (1-Form-A) relays actuated by latched TTL logic-level control signals. The monolithic silicon, which features high voltage DMOS structures and low voltage CMOS circuitry, is biased by a 3.3V power supply eliminating the requirement for external high-voltage supplies for proper operation. Switch-output to logic-input isolation is +/- 320V.
Designed to provide flexible single-ended or differential access to high voltage networks, the CPC7514Z may also be configured as two sets of matched pair- switches for improved differential performance. The switch pairs have an on-resistance matching specification of 0.8 Ohm maximum over the industrial temperature range of -40 to +85 degrees Celsius.
The individual switches have active current-limiting protection for fault events which limits the low frequency currents to 200mA. Under serious high-power fault conditions, which may raise the IC junction temperature, a thermal shutdown protection feature is provided. Between the initial current-limit and the thermal-shutdown events, a secondary, low-level, current-limit mode is provided to limit the power dissipation of the switches. Protection continues until the fault is removed. These features offer robust circuit protection in adverse application environments.
These switch arrays are fabricated using Clare’s bonded-wafer, silicon-on-insulator, BCDMOS process with trench isolation. Clare’s BCDMOS IC process has been used for many years in central office telecom equipment requiring long operational life (17+ years). Clare’s integrated Line Card Access Switch (LCAS) ICs which are fabricated in the same BCDMOS process have replaced many electromechanical 2-Form-C relays, enabling higher density line card designs.
In addition to telecom, the CPC7514Z may be used as four normally open relays in automatic test equipment (ATE), industrial controls, battery monitoring/charging equipment and instrumentation applications. The device may also interface directly with 110Vrms AC in switch applications replacing banks of electromechanical relays (EMRs) and driver circuitry for enhanced system integration. Many applications will benefit from the elimination of a costly DC/DC converter block that is generally incorporated to bias the external EMRs.

Clare Introduces High Efficiency Miniature Solid State Relay
The CPC1014N SSR: 60V, 4-Pin Solid State Relay
Clare has introduced their new miniature 60V, 4-pin SOP, 1-Form-A Solid State Relay. The CPC1014N employs optically coupled, high efficient MOSFET technology and provides 1500Vrms of input/output isolation.
The CPC1014N features 400mA of current handling, 2 Ohms of on-resistance, and fast turn-on and turn-off times. The CPC1014N offers board space savings of at least 20% over the competitor's larger 4-pin SOP, and especially targets security systems, complying with EN50130-4, passive infrared detectors (PIRs), data signaling, and sensor circuitry applications.
The CPC1014N has UL Recognized Component File #E76270, meets EN/IEC 60950-1 requirements, and has CSA Certified Component: Certificate #1172007. This device is a direct, drop-in replacement for the Omron G3VM-61G1 or the Toshiba TLP172A, or can be used as a second source, but requires 33% less input control current making the CPC1014N the most efficient in its class.
The small size of this SSR and its high efficiency make it ideal for portable instruments, for remote control applications, and for controlling valves and actuators in automation and industrial systems.
(12.8.08) Clare introduces their most robust low voltage, high current, Single-Pole Solid State Relays
LCB716 and LBA716 Specifically Target Low Voltage Appliance and Large Industrial Power Distribution Markets
Clare announces the immediate production release of the LCB716, a 1-Form-B solid state relay, and the dual-pole combination LBA716, which integrates independent 1-Form-A and 1-Form-B relays into a single package. Both are 60V devices, with 0.5 and 1.0A of load current, respectively.
These devices use optically coupled relay technology to provide an enhanced 3750Vrms isolation barrier between the input and the output of the relays. The efficient MOSFET switches use Clare's patented OptoMOS architecture and the optically coupled output is controlled by highly efficient GaAlAs infrared LEDs. The 60V LCB716 and LBA716 relays are in addition to the previously released LCA710 and LCA715 (60V, 1.0 and 1.8A load current) 1-Form-A devices.
This family of 60V SSRs offers the highest load current capability in 6- and 8-pin surface mount and DIP packaging and very low on-resistances, ranging from 0.25 to 2.0 Ohms. These low voltage relays specifically target high current electronic switching applications, industrial power distribution, sensor circuitry, and medical equipment (patient/equipment isolation).

Tasavirtatehoreleet CPC1718, CPC1727, CPC177 ja CPC1788 sopivat moniin tehosovelluksiin, kuten teollisuussäätöihin, kuluttajalaitteisiin ja lääketieteellisiin laitteisiin.
Clare on julkaissut neljä uutta puolijohteilla toteutettua 1-Form-A-tyyppistä tasavirtatehorelettä, joiden tyyppimerkinnät ovat CPC1718, CPC1727, CPC1779 ja CPC1788. Kaikkien maksimivirta 25 asteen kotelolämpötilassa on 32 ampeeria.
Releet on asennettu eristettyyn ISOPLUS-264-koteloon ja niiden suurimmat estojännitteet ovat 100, 250, 600 ja 1000 V. Päästösuunnan resistanssit ovat vastaavasti 0,075, 0,090, 0,400 ja 1,250 ohmia.
Näiden releiden kehitystyö perustuu Claren perinteiseen kokemukseen integroiduista valokennopiireistä, johdinkehysrakenteesta sekä monisirukoteloinnista, jossa sovelletaan IXYSin asiantuntemusta tehomosfettien, tehokomponenttien koteloinnin ja sirualustan tekniikasta.
Optisesti kytkettyjä mosfetteja käytettäessä saavutetaan 2500 Vrms eristysjännite tulon ja lähdön välillä, ja kuten kaikissa Claren puolijohdereleissä, optisia lähtöjä ohjaavat GaAIAs-tyyppiset infrapunaledit.
Muitakin Claren tehoreleitä on saatavana Power SIP -koteloissa ja eristetyissä i4-PAC-koteloissa. Power SIP on nastayhteensopiva muiden puolijohdereleiden kanssa, joten siirtyminen olemassa olevista laitteista uusiin on helppoa. i4-PAC-kotelossa on sähköisesti eristetty kuori, jonka terminen resistanssi on korkea, joten se on ihanteellinen ratkaisu teholaitteisiin, joissa tarvitaan jännitteetön, termisesti helposti hallittava jäähdytysripa.
Suuritehoisten 1-Form-A-tyyppisten puolijohdereleiden perhee sisältää markkinoiden tehokkaimmat mosfettipohjaiset puolijohdereleet.

Tehoreleet CPC1708 ja tasavirtamalli CPC1709 sopivat niin teollisuuden, kuluttajalaitteiden kuin lääketieteellisten kojeiden tehon kytkentään
Clare, Inc. on laajentanut sekä vaihto- ja tasavirta- että vain tasavirtakäyttöisten yksinapaisten (1-Form-A) puolijohdetehoreleittensä valikoimaa tyypeillä CPC1708 ja CPC1709, joiden kytkentäkyky on 24A tai 32 A (@Tc=25ºC). Tyyppi CPC1708 on saatavana i4-PAC™-kotelossa. Sen sulkujännite on 60 V ja päästösuunnan resistanssi 0,08 ohmia. Tyyppi CPC1709 puolestaan on ISOPLUS-264-kotelossa ja sen vastaavat arvot ovat 60 V ja 0,05 ohmia.
Näiden tehoreleiden kehitystyö perustuu sekä valikoimaan Claren perinteisiä vahvuuksia valokennopiirien, johdinkehysten rakenteen ja monisirukoteloinnin suunnittelussa että IXYS’in asiantuntemukseen tehomosfettien, tehopiirien koteloinnin ja alustamateriaalien alalla.
Optisesti kytketyt mosfetit mahdollistavat 2500 Vrms eristyksen tulon ja lähdön välillä ja, kuten Claren kaikissa puolijohdereleissä, optista lähtöä ohjaa GaAIAs-tyyppinen infrapunaledi.
Claren tehoreleet ovat nyt saatavana kolmessa erilaisessa kotelossa, nimittäin Power SIP, i4-PAC ja ISOPLUS-264, josta kaksi jälkimmäistä on eristäviä. Power SIP -kotelo on nastayhteensopiva muiden puolijohdereleiden kanssa, joten sekä siirtyminen uudempaan malliin että kokonaan uusien rakenteiden suunnittelu on helppoa.
Tässä RoHS-yhteensopivassa yksinapaisten tehoreleiden perheessä ovat markkinoiden suuritehoisimmat mosfetttipohjaiset puolijodereleet. Sovelluksia ovat mm. moottoriohjaus, teollisuusrobotit, lääketieteelliset laitteet, rautatie- ja tieliikenneohjaus, kuluttajalaitteet, teollisuuden säädöt sekä testaus- ja mittauslaitteet. Releet ovat teollisuussäätöstandardin UL 508 mukaisia.
