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.
The Silicon Carbide power diodes were specifically designed for protection of solar cells arrays in solar panels mounted in satellites and space exploration modules. The first batches of devices are currently used for two European Space Agency missions, BepiColombo and Solar Orbiter.
The activity of product assurance (PA) support performed by Alter technology engineers is being more and more demanded and appreciated by space customers due to the high level of mastering required on components technology knowledge, space requirement/environment understanding, failure mode mechanism, data accessibility/analysis/assessment, margin and derating rules, testing at component/board/equipment level…
For passive devices testing, we have equipment which permits the characterization of the electrical behavior of resistors, capacitors, coils, etc., in a wide range of test conditions and in accordance with their applicable specifications: Measurement and testing of high power devices, Dielectric withstanding, voltage up to 12 KV Characterization on LCR devices up to 3 GHz
The webinar describes circuit-level details of how to use the device in the intended applications and presents some experimental results demonstrating its performance. The RHRPMICL1A device has been recently qualified to the QML-V standard for radiation hardness with SMD number 5962-17211
