Radiation Hardened, SEGR Resistant
N-Channel Power MOSFETs
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 FETs combine this electrical
capability with total dose radiation hardness up to 300K
RADs while maintaining the guaranteed performance for
Single Event Effects (SEE) which the Fairchild FS families
have always featured.
The Fairchild portfolio of Star*Power FETs includes a family
of devices in various voltage, current and package styles.
The Star*Power family consists of Star*Power and
Star*Power Gold products. Star*Power FETs are optimized
for total dose and r
DS(ON)
performance 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
providing 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 TA45216W.
