Bulletin PD-20707 rev. C 03/03 21DQ04 SCHOTTKY RECTIFIER 2 Amp DO-41 Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM VF TJ @ 2 Apk, TJ = 125°C range Description/Features Units A V V °C The 21DQ04 axial leaded Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. Low profile, axial leaded outline High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability 21DQ04 2 40 0.5 - 40 to 150 CASE STYLE AND DIMENSIONS Conform to JEDEC Outline DO-204AL (DO-41) Dimensions in millimeters and inches www.irf.com 1 21DQ04 Bulletin PD-20707 rev.
