Description/Features
The MBR30..WT center tap Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage.
The proprietary barrier technology allows for reliable operation
up to 150° C junction temperature. Typical applications are in
switching power supplies, converters, free-wheeling diodes,
and reverse battery protection.
