N-Channel Power MOSFET
Features
Description
• 3A, 500V, r
= 2.70Ω
The Discrete Products Operation of Fairchild Corporation
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.

• Total Dose
- Meets Pre-RAD Specifications to 100K RAD (Si)
• Single Event
- Safe Operating Area Curve for Single Event Effects

The Fairchild 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.
• Dose Rate
- Typically Survives 3E9 RAD (Si)/s at 80% BV
DSS
- Typically Survives 2E12 if Current Limited to I
DM
• Photo Current
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.
- 8.0nA Per-RAD(Si)/s Typically
