Radiation Hardened, SEGR Resistant
P-Channel Power MOSFETs
The Discrete Products Operation of Intersil 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
hardness 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 Intersil 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)
structure. 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 Intersil Corporation for any desired
deviations from the data sheet.
Formerly available as type TA17797.
