“With this, the SupIR-SMD package is testament to IR HiRel’s commitment to deliver innovation that exceeds the specific requirements of the space market,” said Eric Toulouse, Vice-President and General Manager of IR HiRel.
Traditionally, designers resort to a ‘dead bug’ and lead configuration, where the packages are flipped upside down and soldered to the PCB via leads. Dead bug soldering dissipates heat sub-optimally and decreases MOSFET power capacity. Looking forward, system designers can optimize power system efficiency through direct mount of the SupIR-SMD package to the PCB, enabling the shortest thermal conduction path without any compromise in system reliability.
The SupIR-SMD package is JANS-qualified to MIL-PRF-19500. JANS is the most rigorous level of screening and acceptance requirements available to assure the performance, quality and reliability of discrete semiconductors intended for space flight. The new rad hard MOSFETs are also QPL-qualified in accordance with the Qualified Products List (QPL) for space applications.
The new SupIR-SMD QPL-qualified rad hard MOSFETs can be ordered now with the MIL-PRF-19500 package identifier ‘U2A.’
