SCHOTTKY RECTIFIER
3.3 Amp
Description/Features
Major Ratings and Characteristics
The 31DQ.. axial leaded Schottky rectifier has been opti-
mized for very low forward voltage drop, with moderate
leakage. Typical applications are in switching power sup-
plies, converters, free-wheeling diodes, and reverse
battery protection.
