Dimensions in millimeters and inches Outline C - 16 CASE STYLE AND DIMENSIONS IF(AV) Rectangular 3.3 A waveform VRRM 50/60 V IFSM @ tp = 5 µs sine 340 A VF @ 3 Apk, TJ = 25°C 0.62 V TJ - 40 to 150 °C Characteristics 31DQ.. Units 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. 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 Description/FeaturesMajor Ratings and Characteristics SCHOTTKY RECTIFIER 3.3 Amp 31DQ05 31DQ06 PD-2.305 rev.
