PRELIMINARY DATA SHEET 53258 RADIATION TOLERANT 120VDC – 5A SOLID STATE RELAY Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Features: Design for 100 krad(Si) Total Dose Hermetically Sealed in Surface Mount Package Low On-resistance 5A Continuous Output Current Operation over Full Military Temperature Range -55°C to +125°C Optically Coupled Input / Output Isolation Tested to 1000 VDC Shock and Vibration Resistance Applications: Satellite/Space Systems Military/High Reliability Systems Power Distribution/Switching Solenoid Driver Stepper Motor Driver Switching Heaters DESCRIPTION The 53258 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 53258 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 53258 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 very low RDS(ON) and capable of carrying a continuous current of 5 amperes. This device is designed to function with min...
