Bulletin PD-20590 rev. B 11/04 1N5818 1N5819 SCHOTTKY RECTIFIER 1.0 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 µs sine VF TJ @ 1 Apk, T J = 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 Lead-Free plating Values 1.0 30/40 225 0.55 - 40 to 150 CASE STYLE AND DIMENSIONS Device Marking: 1N581X Conform to JEDEC Outline DO-204AL (DO-41) Dimensions in millimeters and inches www.irf.com 1 1N5818, 1N5819 Bulletin PD-20590 rev.
