Characteristics
160CMQ... Units
The 160CMQ isolated, center tap Schottky rectifier module
series 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, convert-
ers, free-wheeling diodes, and reverse battery protection.
