Description

The Intersil has designed a series of SECOND GENERATION hardened power
MOSFETs of both N and P channel enhancement types with ratings from 100V to
500V, 1A to 60A, and on resistance as low as 25mΩ. Total dose hardness is
offered at 100K RAD(Si) and 1000KRAD(Si) with neutron hardness ranging from
1E13n/cm
(GAMMA DOT) exists for rates to 1E9 without current limiting and 2E12 with cur­rent limiting.

This MOSFET is an enhancement-mode silicon-gate power field effect transistor of
the vertical DMOS (VDMOS) structure. It is specially designed and processed to
exhibit minimal characteristic changes to total dose (GAMMA) and neutron (n
exposures. Design and processing efforts are also directed to enhance survival to
heavy ion (SEE) and/or dose rate (GAMMA DOT) exposure.
