Description/ Features
The 50SQ... axial leaded Schottky rectifier series has been
optimized for low reverse leakage at high temperature. The
proprietary barrier technology allows for reliable operation
up to 175C junction temperature. Typical applications are
in switching power supplies, converters, free-wheeling di-
odes, and reverse battery protection.
