December 1998
File Number 4637
Formerly Available As FSF450R4,
Radiation Hardened, SEGR Resistant,
N-Channel Power MOSFETs
Features
• 9A, 500V, r
= 0.600Ω
DS(ON)
• Total Dose
The Discrete Products Operation of Intersil 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
- Meets Pre-RAD Specifications to 100K RAD (Si)
• Single Event
- Safe Operating Area Curve for Single Event Effects

- SEE Immunity for LET of 36MeV/mg/cm with V
up
DS
of 10V Off-Bias
to 80% of Rated Breakdown and V
GS
• Dose Rate
- Typically Survives 3E9 RAD (Si)/s at 80% BV
environments. The dose rate and neutron tolerance
necessary for military applications have not been sacrificed.
DSS
- Typically Survives 2E12 if Current Limited to I
DM
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.
• Photo Current
- 30nA Per-RAD(Si)/s Typically
• Neutron
- Maintain Pre-RAD Specifications
for 3E12 Neutrons/cm
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.
