The MBR16.. Schottky rectifier has been optimized for low
reverse leakage at high temperature. The proprietary barrier
technology allows for reliable operation up to 150° C junction
temperature. Typical applications are in switching power sup-
plies, converters, free-wheeling diodes, and reverse battery
protection.
