70A, 100V, 0.022 Ohm, Rad Hard,
SEGR Resistant, N-Channel Power MOSFETs
Description
The Discrete Products Operation of Fairchild Corporation
has developed a series of Radiation Hardened MOSFETs
specifically designed for commercial and military space
applications. Enhanced Power MOSFET immunity to Single
Event Effects (SEE), Single Event Gate Rupture (SEGR) in
particular, is combined with 100K RADS of total dose hard-
ness to provide devices which are ideally suited to harsh
space environments. The dose rate and neutron tolerance
necessary for military applications have not been sacrificed.
The Fairchild portfolio of SEGR resistant radiation hardened
MOSFETs includes N-Channel and P-Channel devices in a
variety of voltage, current and on-resistance ratings.
Numerous packaging options are also available.
This MOSFET is an enhancement-mode silicon-gate power
field-effect transistor of the vertical DMOS (VDMOS) struc-
ture. It is specially designed and processed to be radiation
tolerant. The MOSFET is well suited for applications exposed
to radiation environments such as switching regulation,
switching converters, motor drives, relay drivers and drivers
for high-power bipolar switching transistors requiring high
speed and low gate drive power. This type can be operated
directly from integrated circuits.
Reliability screening is available as either commercial, TXV
equivalent of MIL-S-19500, or Space equivalent of
MIL-S-19500. Contact Fairchild for any desired deviations
from the data sheet.
