Radiation Tolerant 120VDC – 5A Power MOSFET Optocoupler

The 53258 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.
