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 25m

Ω. Total dose hardness is

offered at 100KRAD(Si) and 1000KRAD(Si) with neutron hardness ranging from

(GAMMA DOT) exists for rates to 1E9 without current limiting and 2E12 with cur-

rent 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

exposures. Design and processing efforts are also directed to enhance survival to

heavy ion (SEE) and/or dose rate (GAMMA DOT) exposure.

This part may be supplied as a die or in various packages other than shown

above. Reliability screening is available as either non TX (commercial), TX equiv-

alent of MIL-S-19500, TXV equivalent of MIL-S-19500, or space equivalent of

MIL-S-19500. Contact the Intersil High-Reliability Marketing group for any

desired deviations from the data sheet.
