Radiation Hardened, SEGR Resistant
N-Channel Power MOSFET
Fairchild Star*Power Rad Hard
MOSFETs have been specifically
developed for high performance
applications in a commercial or
military space environment.
Star*Power MOSFETs offer the system designer both
extremely low r
DS(ON)
and Gate Charge allowing the
development of low loss Power Subsystems. Star*Power
Gold FETs combine this electrical capability with total dose
radiation hardness up to 100 krads while maintaining the
guaranteed performance for Single Event Effects (SEE)
which the Fairchild FS families have always featured.

The Fairchild family of Star*Power FETs includes a series of
devices in various voltage, current and package styles. The
portfolio consists of Star*Power and Star*Power Gold
products. Star*Power FETs are optimized for total dose and
r
DS(ON)
while exhibiting SEE capability at full rated voltage
up to an LET of 37. Star*Power Gold FETs have been
optimized for SEE and Gate Charge combining SEE
performance to 80% of the rated voltage for an LET of 82
with extremely low gate charge characteristics.
This MOSFET is an enhancement-mode silicon-gate power
field effect transistor of the vertical DMOS (VDMOS)
structure. It is specifically designed and processed to be
radiation tolerant. The MOSFET is well suited for
applications exposed to radiation environments such as
switching regulation, switching converters, power
distribution, motor drives and relay drivers as well as other
power control and conditioning applications. As with
conventional MOSFETs these Radiation Hardened
MOSFETs offer ease of voltage control, fast switching
speeds and ability to parallel switching devices.
Reliability screening is available as either TXV or Space
equivalent of MIL-PRF-19500.
Formerly available as type TA45222W.
