Description

The 20TQ...PbF 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 junction temperature. Typical applications of 20TQ045 are in switching power supplies, converters, freewheeling diodes, and reverse battery protection.
