Description
The Discrete Products Operation of Intersil Corporation has
de v eloped a series of Radiation Hardened MOSFETs specif-
ically designed for commercial and military space applica-
tions. Enhanced Power MOSFET immunity to Single Event
Eff ects (SEE), Single Ev ent 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 por tfolio 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
e xposed 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.
