DESCRIPTION

The 20TQ... Schottky rectifier 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, converters, freewheeling diodes,

and reverse battery protection.
