MOSFET commercial plastic components survey and its SEE behaviour

ABSTRACT

In recent years, the use of commercial quality parts in the Space market has been increasing, driving the different actors to find commercial components with sufficiently robust technology to withstand space radiation.

Among all the radiation-sensitive families, MOSFET (Me.tal-Oxide-Semiconductor Field Effect Transistor) transistors are key in modern electronic equipment. They are incorporated in a wide variety of power control and conversion applications for space and the military. Furthermore, in the more recent and advanced satellite systems, there is a trend to use distributed power distribution architectures, such as Point of Load (PoL) power supplies. Despite de numerous advantages that this architecture has, indeed, it usually implies using state-of-the-art MOSFET with lower Qg, which are not always available with a rad-hard technology. Still, they are available as a COTS component.
