Description
The Intersil Corporation has designed a series of SECOND GENERATION hard-
ened 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 25mW. Total dose
hardness is offered at 100K RAD(Si) and 1000KRAD(Si) with neutron hardness
ranging from 1E13n/cm
2
for 500V product to 1E14n/cm
2
for 100V product. Dose
rate hardness (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
o
)
exposures. Design and processing efforts are also directed to enhance survival to
heavy ion (SEU) 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
equivalent of MIL-S-19500, TXV equivalent of MIL-S-19500, or space equiva-
lent of MIL-S-19500. Contact the Intersil High-Reliability Marketing group for
any desired deviations from the data sheet.
CAUTION: Beryllia Warning per MIL-S-19500
refer to package specifications.
