s TYPICAL R_DS(on) = 0.75 Ω
s EXTREMELY HIGH dv/dt CAPABILITY
s 100% AVALANCHE TESTED
s NEW HIGH VOLTAGE BENCHMARK
s GATE CHARGE MINIMIZED
DESCRIPTION
The PowerMESH™II is the evolution of the first
generation of MESH OVERLAY™. The layout re-
finements introduced greatly improve the Ron*area
figure of merit while keeping the device at the lead-
ing edge for what concerns switching speed, gate
charge and ruggedness.
APPLICATIONS
s HIGH CURRENT, HIGH SPEED SWITCHING
s SWITH MODE POWER SUPPLIES (SMPS)
s DC-AC CONVERTERS FOR WELDING
EQUIPMENT AND UNINTERRUPTIBLE
