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. 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 RDS(ON) and capable of carrying a continuous current of 2 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.

Non-repetitive, pulse width ≤ 100 µs, TC = 25°C. 2. Input pins shorted together and output pins shorted together. 3. Input-output potential applied momentarily, not a steady state operating condition. 4. Rise time is measured from 10% to 90% of load current (90% to 10% of VO). Fall time is measured from 90% to 10% of load current (10% to 90% of VO). 5. The user should apply the appropriate transient suppression technique to the output terminals of the relay when the loads are inductive enough to generate voltage spikes.
