SCHOTTKY RECTIFIER 1.0 Amp
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 µs sine VF TJ @ 1 Apk, TJ = 25°C range
Description/Features Units
A V A V °C The 1N5818/ 1N5819 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
