DESCRIPTION
This series of POWER MOSFETS represents the
most advanced high voltage technology. The optimized cell layout coupled with a new proprietary
edge termination concur to give the device low
R
and gate charge, unequalled ruggedness
DS(on)
and superior switching performance.
APPLICATIONS
■ HIGH CURRENT, HIGH SPEED SWITCHING
■ SWITCH MODE POWERSUPPLIES (SMPS)
■ DC-AC CONVERTERS FOR WELDING
