SCHOTTKY RECTIFIER 80 Amp
TO-247AC
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VRRM IFSM VF TJ @ tp = 5 s sine @ 40 Apk, TJ= 125C (typical) per leg range
Description/Features Units
A V A V This center tap Schottky rectifier has been optimized for ultra low forward voltage drop specifically for 1.5V output power supplies. The proprietary sub-micron technology allows for low power loss both in forward and reverse conduction. 125 C TJ operation Center tap configuration Ultra low forward voltage drop High frequency operation High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance
