Micropac Industries, Inc. Power Switching solid state relays 53250

The 53250 is a radiation tolerant Power MOSFET Optocoupler 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 device 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 opencollector TTL. Output is provided by a power MOSFET exhibiting very low RDS(ON) and capable of carrying a continuous current of 10 amperes. This design has demonstrated it will function with minimal degradation after exposure to 100 krad (Si) total dose. This device is available in a variety of quality levels from COTS to class K including any custom screening requirements. The basic datasheet part is environmentally screened to H level in accordance with Table C-IX of MIL-PRF-38534. RADIATION TOLERANT This device contains radiation hardened components and/or other features that provide a level of radiation tolerance. Micropac does not guarantee any level of radiation hardness. Specific lot testing is required to determine the level of radiation hardness. Micropac does not offer this device as compliant to Appendix G (RHA Requirements) of MIL-PRF-38534.
