Rad hard hybrid DC-DC converters From a few watts to hundreds of watts with options for parallel operation and redundant systems
Note that Infineon Technologies recently sold its HiRel DC-DC converter business to Micross. Read the press release.
Infineon offers a large portfolio of rad hard hermetic, hybrid DC-DC converters and PCB open frame and enclosed power supplies for satellite bus platform systems and payloads. Backed by our vast space heritage, customers can source high-reliability, qualified products that reduce mission risk and time to launch. Our flight-proven DC-DC converters are easy to design in and can be used as is with confidence in a wide range of applications, with no de-rating or additional circuitry.
Infineon’s IR HiRel rad hard hybrid DC-DC converter offering includes:
Hermetic hybrid DC-DC converters
- General purpose and application-specific DC-DC converters, including MIL-STD-461 filters
- Standard and advanced functionality and protections
- Qualified to MIL-PRF-38534 Class K, many available as Standard Microcircuit Drawing
- License-free exportable (EAR99) options
- Radiation Hardened Assurance (RHA) plan
- Immunity to TID, SEE, neutron and prompt dose radiation environments in space
- End-of-life performance verification with supporting design analyses for use as is, with no additional de-rating in most applications
- Mission specific radiation environment testing and analysis
PCB open frame and enclosed power supplies
Infineon’s IR HiRel rad hard PCB-based open frame or enclosed power supply units (PSU) deliver high power conversion efficiency and excellent overall performance, while supporting
- High current
- High power
- Complex designs
- Advanced topology and magnetic design
We deliver a range of standard platforms based on a general design philosophy which can be tailored to the customer’s program requirements. Design practices follow military standards and de-ratings.
All models and variants can be supplied with full data analysis package. Contact us with your specific rad hard power needs
IR HiRel offers custom converters based on the standard hybrid series, as well as open-frame PWB converter platforms. Contact sales for further information.

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-38534/MIL-STD-883 are the controlling specifications for power hybrids. MIL-STD-883 directs hybrids to 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.
Screening and Quality Conformance Inspection Requirements
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.
