DESCRIPTION

The 53257 is a 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 53257 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.

RADIATION TOLERANT

Applications:

Satellite/Space Systems

•

Military/High Reliability Systems

•

Power Distribution/Switching

•

Solenoid Driver

•

Stepper Motor Driver

•

Switching Heaters

PRODUCTS DIVISION

Functionally, the device operates as a single-pole single-throw, normally open (1 Form A) DC solid-state relay. The
53257 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 low R
amperes. This device is designed to function with minimal degradation after exposure to 100 krad(Si) total dose.
This device is available in a variety of quality of 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.
