DESCRIPTION

The 53246 is a SPST, radiation tolerant, DC solid-state re lay (SSR) designed for milit ary 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 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, whic h can be supplied from standard logic types such as a standard TTL device. Output is provided by a power MOSFET exhibiting very low R DS(ON) and capable of carrying a continuous current of 2 amperes. This design has demonstrated it will function wi th minimal degradation after exposure to 100 krad (Si) total dose. The 53246 is availabl e in a variety of quality levels from 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. ABSOLUTE MAXIMUM RATINGS WEIGHT: 3.7 grams (typical
