53255

53255 400VDC – 10A SOLID STATE RELAY Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Features: Applications: Hermetically Sealed Package 10A Continuous Output Current Optically Coupled Input/Output Isolation Tested to 1000 VDC Shock and Vibration Resistant Power Distribution/Switching Solenoid Driver Stepper Motor Driver Switching Heaters DESCRIPTION The 53255 is a DC solid state relay (SSR) designed for high reliability commercial applications. This light weight device is resistant to damage from severe shock and vibration, and is immune to contact related problems inherent in electro-mechanical relays. The SSR is enclosed in a hermetic metal package to ensure reliability in harsh environments. Effective isolation of 1000 VDC between control and load circuits is achieved through the use of optical coupling. Functionally, the device operates as a single-pole single-throw, normally open (1 Form A) DC solid-state relay. The SSR is actuated by an input current of 5 to 15 mA, which can be supplied from standard logic types such as opencollector TTL. Output is provided by a power MOSFET capable of carrying a continuous current of 10 amperes.
