30CTQ...PbF Series
SCHOTTKY RECTIFIER
30 Amp
IF(AV) = 30Amp
VR = 80 - 100V
Description/ Features
Major Ratings and Characteristics
This center tap Schottky rectifier series has been optimized
for low reverse leakage at high temperature. The proprietary
barrier technology allows for reliable operation up to 175°C
junction temperature. Typical applications are in switching
power supplies, converters, free-wheeling diodes, and reverse battery protection.
