CPC1511 enhances the robustness of relay applications
IXYS Integrated Circuits Division (ICD) announced the immediate production release of the CPC1511, a current limiting 1-Form-A normally open Solid State Relay (SSR) that replaces electromechanical devices while enhancing the performance of switching applications.
The 230V CPC1511 is manufactured with an optically isolated control input, and an integrated monolithic die for the output current. Fabricated with ICD’s HVIC SOI technology, the device is an integrated powered driver with active current limiting and thermal shutdown circuitry and Power MOSFET switches. CPC1511 incorporates thermal shutdown circuitry for improved survivability in harsh environments and is designed to pass regulatory voltage surge requirements when provided with appropriate over voltage protection circuitry. This device is designed specifically for harsh AC or DC applications where printed circuit board space is at a premium and additional power supplies are not available. The active current limit and thermal shutdown features offer automatic recovery to the appropriate switch state, as determined by the input control current, once the fault condition is removed. This fault protection circuitry provides excellent robustness in high stress switching environments.
The CPC1511 relay provides current limiting for unidirectional DC applications, in addition to typical AC applications. This current limiting 1-Form-A normally open SSR is ideal for general power switching applications in instrumentation, IoT products, industrial controls, peripherals, security, and medical equipment. Key features include built-in current-limiting protection circuitry, thermal shutdown, linear AC/DC operation, low power consumption, clean, bounce-free switching, and an extended operational lifetime over electromechanical relays.
The CPC1511 is available in a 4-Pin Power SIP Package (25/Tube).
