DESCRIPTION
The 52CPQ030 center tap Schottky rectifier series 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 supplies, converters, freewheeling diodes,
and reverse battery protection.
