Together, we offer a broad selection of solutions certified to European Space Agency (ESA) and Defense Logistics Agency (DLA) standards for our global customers. We focus on the quality and reliability of our power conversion solutions, reducing your development effort and risk, so that you can meet requirements faster and work smarter.

Our power conversion portfolio is the industry’s broadest, spanning rad hard MOSFETs, DC-DC hybrid converters and custom PWB-based power supplies. Our flexible custom model can tailor power solutions to your specific needs. Contact us with your requirements.

 

 

Quality Documents


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-38535/MIL-STD-883 are the controlling specifications for integrated circuit semiconductors, voltage regulators, operational amplifiers, DC-DC converters and filters. MIL-STD-883 directs these products to be manufactured to class level B or class level S.

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. The HiRel Products Group also provides screened plastic encapsulated devices.

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.
