DESCRIPTION
The PowerMESHTMII is the evolution of the first TO-247
generation of MESH OVERLAYTM. 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 swithing speed, gate INTERNAL SCHEMATIC DIAGRAM
charge and ruggedness.

APPLICATIONS
s SWITH MODE LOW POWER SUPPLIES
(SMPS)
s HIGH CURRENT, HIGH SPEED SWITCHING

s DC-AC CONVERTERS FOR WELDING

EQUIPMENT AND UNINTERRUPTIBLE
