The space community has long resisted the use of COTS due to inherent risks and uncertainties in the process, including lot traceability, validity of radiation test results, test program correlation, and lack of manufacturer warranty and support.
Microchip takes a proven automotive-qualified device and improves the silicon process to make the component immune to single-event latch-up in heavy ions, thus preventing destruction in the radiation environment of space.
Analog Devices has established three commercial space product screening and qualification flows to address New Space needs, designed to offer the best price/reliability ratio for applications targetting different requirements
Power MOSFET’s are a key element of many electronic designs where high power management is needed. They are used in almost any power supply application (for example as switches). However, the fact that they are key, doesn’t mean necessarily that we have a wide number of rad-hard power MOSFET providers.
