Formerly FSS234R4
6A, 250V, 0.600 Ohm, Rad Hard,
N-Channel Power MOSFET
Features
• 6A, 250V, r
• Total Dose
= 0.600Ω
DS(ON)
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 environ-
ments. The dose rate and neutron tolerance necessary for
military applications have not been sacrificed.
- 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
DSS
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. Numer-
ous packaging options are also available.
- Typically Survives 2E12 if Current Limited to I
DM
• Photo Current
- 4.0nA Per-RAD(Si)/s Typically
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 oper-
ated directly from integrated circuits.
• Neutron
