The CPC1561B normally open solid-state relay (SSR) offers 1 A, 60 V and integrates both current limiting and thermal shutdown circuits. The small, surface-mount device’s dual fault protection provides a rugged solution not possible when using electro-mechanical relays and standard SSRs. It enhances electronics capabilities to survive fault conditions through active current limiting and adapts to fault conditions using thermal shutdown fault mode protection at 128 °C die temperature. It also reduces equipment downtime by using recovery with auto-reset capabilities, thus avoiding system failures. It offers input/output galvanic isolation via 3,750 Vrms input-to-output isolation.
