SCHOTTKY RECTIFIER

110 Amp

New GenIII D-61 Package

Major Ratings and Characteristics

Description/Features

The 111CNQ045A center tap Schottky rectifier module has

beenoptimizedforverylowforwardvoltagedrop, withmoder-

ate leakage. The proprietary barrier technology allows for

reliable operation up to 175 °C junction temperature. Typical

applicationsareinswitchingpowersupplies,converters,free-

wheeling diodes, and reverse battery protection.
