Description/Features
The 110CNQ045A center tap Schottky rectifier module 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.
