SCHOTTKY RECTIFIER
15 Amp
IF(AV) = 15Amp
VR = 35/ 45V
Major Ratings and Characteristics
Description/ Features
The MBR15.. center tap Schottky rectifier has been optimized
for low reverse leakage at high temperature. The proprietary
barrier technology allows for reliable operation up to 150° C
junction temperature. Typical applications are in switching
power supplies, converters, free-wheeling diodes, and reverse battery protection.
