IF(AV) Rectangular waveform VRRM IFSM VF TJ @ tp = 5 s sine @ 1.0 Apk, TJ=125C range
Description/Features
The MBRS190TR, MBRS1100TR surface-mount Schottky rectifier has been designed for applications requiring low forward drop and very small foot prints on PC boards. Typical applications are in disk drives, switching power supplies, converters, free-wheeling diodes, battery charging, and reverse battery protection. Small foot print, surface mountable Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability
