RAD LEVEL SCREENING LEVEL PART NUMBER/BRAND
10K Commercial FSJ9055D1
Formerly available as type TA17750.
The Discrete Products Operation of Harris Semiconductor
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 Harris 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 regula-
tion, 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 Harris Semiconductor for any
desired deviations from the data sheet.
CAUTION: Beryllia Warning per MIL-S-19500
refer to package speciﬁcations.
CAUTION: These devices are sensitive to electrostatic discharge. Users should follow proper IC Handling Procedures.
