53258 RADIATION TOLERANT
120VDC – 5A POWER MOSFET OPTOCOUPLER Mii MICROCIRCUITS 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 radiation tolerant Power MOSFET Optoc oupler 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 dev ice is enclosed in a hermetic metal package to ensure reliability in harsh environments. Effe ctive isolation of 1000 VDC between c ontrol and load circuits is achieved through the use of optical coupling. Functionally, the device operates as a single-pole single-th row, 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 minimal degradation after exposure to 100 krad(Si) total dose. The 53258 SSR 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. ABSOLUTE MAXIMUM RATINGS RADIATION TOLERANT This device contains radiation har dened components and/or other features t hat provide a level of radiation tolerance. Micropac does not guarantee any level of radi ation 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.

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 suppr ession technique to the output terminals of the relay when the loads are inductive enough to generate voltage spikes.
