Overview: JANSR2N7408
Data Sheet December 1998 File Number
4637 Formerly Available As FSF450R4, Radiation Hardened, SEGR Resistant, N-Channel Power MOSFETs
The Discrete Products Operation of Intersil has developed a series of Radiation Hardened MOSFETs specifically designed for mercial and military space applications. Enhanced Power MOSFET immunity to Single Event Effects (SEE), Single Event Gate Rupture (SEGR) in particular, is bined 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. Also available at other radiation and screening levels. See us on the web, Intersil’ home page: http://.semi.intersil..
