DESCRIPTION

The 53274 is a Power MOSFET Optocoupler desi gned for military 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 device is enclosed in a hermetic metal package to ensure r eliability 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 r elay. The SSR is actuated by an input current of 5 to 15 mA, which can be supplied from standard logic types such as open - collector TTL. Output is provided by a power MOSFET exhibiting very low R DS(ON) and capable of carrying a continuous current of 10 amp eres. The basic data sheet part is environmentally screened to H level in accordance with Table C-IX of MIL-PRF -38534. ABSOLUTE MAXIMUM RATINGS
