This light-weight device is resistant to damage from severe shock and vibration, and is immune to contact related problems inherent in electromechanical relays. The device 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 exhibiting very low RDS(ON) and capable of carrying a continuous current of 10 amperes. The basic data sheet part is environmentally screened to H level in accordance with Table C-IX of MIL-PRF -38534. ABSOLUTE MAXIMUM RATINGS Output Voltage..............................................
