JANSR2N7408
Data Sheet December 1998 File Number
Formerly Available As FSF450R4,
Radiation Hardened, SEGR Resistant,
N-Channel Power MOSFETs
The Discrete Products Operation of Intersil has developeda
series of Radiation Hardened MOSFETs specifically
designed for commercial and military space applications.
Enhanced Power MOSFET immunity toSingleEvent 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.
