16 Amp, 45 Volt Rating Center-Tap Rectifier

FEATURES

•Very Low Forward Voltage

•Low Recovery Charge

•Rugged Package Design, (JEDEC TO-257AA)

•High Efficiency For Low Voltage Supplies

•45V Blocking @ Rated Tjmax

•50V Repetitive Surge Voltage

•Dual Schottky Rectifier In A Single Isolated Package
