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 RDS(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.

53246 Radiation Tolerant 40VDC - 2A Solid State Relay
Non-repetitive, pulse width 10 ms, TC = 25C (see Figure 6). Non-repetitive, pulse width 100 s, TC = 25C. Case Temperature TC = 25C (see Figure 7). Input pins shorted together and output pins shorted together. Input-output potential applied momentarily, not an operating condition. 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). CAUTION: Care should be taken so as not to exceed the maximum power dissipation and maximum junction temperature when repetitively switching loads.
