Radiation Hardened, SEGR Resistant

P-Channel Power MOSFETs

The Discrete Products Operation of Intersil has developed a

series of Radiation Hardened MOSFETs specifically

designed for commercial and military space applications.

Immunity to Single Event Effects (SEE) is combined with

100K RADs of total dose hardness 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.

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)

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.

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.

Formerly available as type TA17750T.
