MOSFETs in new patented SMD0.2 package drastically reduce system size and weight in HiRel space applications

International Rectifier has launched a family of hermetic radiation hardened (RAD-Hard) 100 V MOSFETs in a new compact, surface mount SMD0.2 package for space applications such as satellite bus power systems and payload power supplies. IR’s new patented, hermetic, compact SMD0.2 package utilizing Aluminum Nitride (AlN) ceramic for enhanced thermal conductivity, is designed specifically for RAD-Hard MOSFETs and addresses the needs of power designers requiring reduced weight and system size. With a 0.3” x 0.2” x 0.1” (8mm x 5mm x 3mm) footprint weighing only 0.25 g, the SMD0.2 surface mount package is 50 percent smaller and 75 percent lighter compared to existing SMD0.5 packages while dissipating the same amount of power at around 23 W.
