Features, Applications

IF(AV) Rectangular waveform VRRM IFSM 5 �s sine @ 5 Apk, = 125�C range V �C

The 50WQ03FN 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 moutable Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability
