Micropac Industries, Inc. Power Switching solid state relays 53258

The 53258 is a radiation tolerant Power MOSFET Optocoupler designed for military and space 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 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 53258 SSR is actuated by an input current of 5 to 15 mA, which can be supplied from a standard TTL device. Output is provided by a power MOSFET exhibiting very low RDS(ON) and capable of carrying a continuous current of 5 amperes. This device is designed to function with minimal degradation after exposure to 100 krad(Si) total dose. The 53258 SSR is available in a variety of quality levelsfrom COTS to class K including any custom screening requirements. The basic data sheet part is environmentally screened to H level in accordance with Table C-IX of MIL-PRF-38534.
