SCHOTTKY RECTIFIER
2 Amp
DO-41
Major Ratings and Characteristics
Description/Features
The 21DQ04 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.
