LITTELFUSE CPC1561B Solid State Relay | New Product Brief
This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
LITTELFUSE CPC1561B Solid State Relay
IXYS CPC1561B Solid State Relays can be used in place of electromechanical relays while providing enhanced robustness. CPC1561B SSRs can switch continuous AC or DC load currents up to 1A and block up to 60V. They have built-in active current limit control that uses integrated current sensing to regulate the gate drive and limit current during fault conditions. They also have a thermal shutdown function to prevent the SSR from overheating while current limiting is active, while auto-recovery functionality allows for seamless operation once the fault is removed.
The CPC1561B operates with low power consumption, with an efficient LED and a photodiode array providing actuation control and delivering 3750VRMS isolation between the input and output. The SSRs are designed for use in harsh environments and have a UL 94 V-0 flammability rating.
