Considerations for Designs Using Radiation-Hardened Solid State Relays
HiRel Solid State Relays
IR HiRel’s solid state relay (SSR) portfolio includes radiation-hardened (rad hard) single, dual and octal devices in hermetically sealed packages and tested up to 100kRads(Si) total ionizing dose. The family includes optically coupled, buffered and non-buffered solid state relays, with input and output MOSFETs using IR HiRel’s industry-leading rad hard MOSFET technology. Customers choose our SSRs for high-reliability applications including solar array management, heater controls, bus switching, and ground power isolation.
In addition to our standard solid state relays, we also offer custom space-grade power control modules designed to customers’ specifications. Contact us with your requirements.

Quality Conformance Testing |
|
Unlike standard commercial products, HiRel products must be submitted to various levels of quality conformance testing to ensure that the products are capable of performing to specifications in the often harsh environments of military and space applications. Both the United States and European community have each developed specifications that detail the sequence of quality conformance testing. In the United States, the Defense Logistics Agency (DLA) is the controlling agency and has issued specifications that govern the quality conformance testing sequence performed on semiconductor devices and hybrid modules, namely MIL-PRF-19500/MIL-STD-750, MIL-PRF-38534/MIL-STD-883 and MIL-PRF-38535/MIL-STD-883. MIL-PRF-19500/MIL-STD-750 are the controlling specifications for discrete semiconductors such as diodes and power MOSFETs. MIL-PRF-19500 directs discrete semiconductors to be manufactured to either JAN, JANTX, JANTXV, or JANS levels (Note: the JAN level is not allowed for MOSFETs). MIL-PRF-38534/MIL-STD-883 are the controlling specifications for power hybrids. MIL-STD-883 directs hybrids te be manufactured to class H or class K. International Rectifier HiRel Products Group manufactures and tests hermetic products to one of three distinct quality conformance levels: (1) commercial hermetic, (2) source control drawing (SCD), or (3) MIL-PRF-38534, MIL-PRF-38535 qualified. |

Glossary Class H: Class H is the standard military quality level provided in MIL-PRF-38534, General Specification for Hybrid Microcircuits. It is intended for space applications. Level B: Class level B defines the screening requirements for high reliability military applications as specified in MIL-STD-883 and is intended for use in class H products. Level S: Class level S defines the screening requirements for high reliability space applications as specified in MIL-STD-883 and is intended for use in class K products. JAN: JAN (Joint Army Navy) is the prefix assigned by the DLA to designate devices on the DLA qualified parts list. JANTX: Military screening level as specified in MIL-PRF-19500 for a DLA qualified device. JANTXV: Military with visual inspection screening level as specified in MIL-PRF-19500 for a DLA qualified device. JANS: Space level screening as specified in MIL-PRF-19500 for a DLA qualified device. |
