Radiation Effects on MOSFET Semiconductor Devices in Support of Leo Operations
Abstract
In this research, we exposed the Infineon BSC060N10NS3GATMA1 power metal oxide semiconductor field-effect transistor (MOSFET) to x-ray radiation and tested the device to failure by monitoring its voltage threshold. We found the MOSFET failed at approximately 7 krads under biased conditions versus 24 krads when held at ground (to simulate spare parts). Applying 2 mm of aluminum shielding to the MOSFET increased the survivability by roughly a factor of three. Based on the results from the radiation testing, we used the SPace ENVironment Information System (SPENVIS) to identify 5-year low Earth orbit (LEO) satellite orbits that would support the devices radiation tolerance.
