31DQ06 Datasheet | International Rectifier

Description /Features Units A V A V °C The 31DQ.. 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 31DQ.. 3.3 50/60 340 0.62 - 40 to 150 CASE STYLE AND DIMENSIONS Outline C - 16 Dimensions in millimeters and inches 31DQ05, 31DQ06 PD-2.305 rev.
