Littelfuse/IXYS CPC1510GSTR

The CPC1510 is a single-pole, normally open (1-Form-A) Solid State Relay with an integrated current limit feature that can replace electromechanical relays while enhancing the robustness of wireline-interface applications. The relay is constructed using a GaAIAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated technology, comprises a photodiode array, switch control with active current limiting circuitry, and MOSFET switches. The active current limit circuitry in the CPC1510 also provides a thermal shutdown feature offering excellent power cross immunity for improved survivability in harsh environments. These enhancements greatly improve the robustness of end systems using this device compared to systems using relays without the integrated current limit. In addition, the active current limit circuitry enables the CPC1510 to pass FCC 68.302 and other regulatory voltage surge requirements when adequate overvoltage protection is provided. The CPC1510 relay may be used in both unidirectional DC applications as well as bi-directional AC applications.
