Rad Hard & Standard Hermetic MOSFETs

 

IR HiRel is a leader in radiation-hardened (rad hard) power MOSFETs, being the first manufacturer to offer rad hard power MOSFETs for space in 1985. Over the last three decades, IR HiRel has continuously innovated in silicon design, packaging technology and quality with US DoD DLA QPL products up to MIL-PRF-19500 JANS level.

IR HiRel offers a broad selection of standard and rad hard MOSFETs in a wide range of hermetic packaging options screened to MIL-PRF-19500 and available as QPLs.

Customers benefit from IR HiRel’s unparalleled expertise in power MOSFET radiation testing, and our products and solutions engineered for optimal performance and longevity in extreme environmental conditions, including exposure to severe ionizing radiation in space. IR HiRel offers the broadest portfolio of space power MOSFETs for applications in geosynchronous and geostationary orbit, Medium Earth Orbit (MEO) and Low Earth Orbit (LEO). Our rad hard MOSFET portfolio includes license-free exportable products, as well as radiation hardness ratings up to 1 Mrad(Si) TID and 86 MeV.cm2/mg LET.

IR HiRel’s latest generation of rad hard power MOSFET technology outperforms the competition with a 30 percent improvement in FoM (RDSon x Qg).

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).

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.

Screening and Quality Conformance Inspection Requirements

QPL Listing - Discretes

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.
