Use of pre-irradiated commercial MOSFETs in a power supply hardened to withstand gamma radiation

Technical Article – Authors: M. Marceau – H. Huillet – P. Marchand

Abstract:

This article describes the approach used to design a hardened power supply capable of operating to a total gamma irradiation dose of 1Mrad(Si). Pre-irradiation of power MOSFETs proved to be necessary, and the paper also discusses the effects of this treatment.
