DESCRIPTION
The 53246 is a SPST, radiation tolerant, DC solid-state relay (SSR) 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 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 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 with minimal degradation after
exposure to 100 krad (Si) total dose. The 53246 is available 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.
