Description

The Discrete Products Operation of Intersil Corporation has

developed a series of Radiation Hardened MOSFETs specif-

ically designed for commercial and military space applica-

tions. Enhanced Power MOSFET immunity to Single Event

Effects (SEE), Single Event Gate Rupture (SEGR) in particu-

lar, is combined with 100K RADS of total dose hardness to

provide devices which are ideally suited to harsh space envi-

ronments. 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) 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.

Reliability screening is available as either commercial, TXV

equivalent

of

MIL-S-19500,

or

Space

equivalent

of

MIL-S-19500. Contact Intersil for any desired deviations

from the data sheet.
