SCHOTTKY RECTIFIER 3.5 Amp
IF(AV) = 3.5Amp VR = 30V
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 3 Apk, TJ = 125C range
Description/ Features Units
A V A V C The 30WQ03FNPBF surface mount Schottky rectifier has been designed for applications requiring low forward drop and small foot prints on PC board. Typical applications are in disk drives, switching power supplies, converters, free-wheeling diodes, battery charging, and reverse battery protection. Popular D-PAK outline Small foot print, surface mountable Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Lead-Free ("PbF" suffix)
