JANSR2N7401

6A, 250V, 0.600 Ohm, Rad Hard,

N-Channel Power MOSFET

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.

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.

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.

Also available at other radiation and screening levels. See us
