Description/Features

The 90SQ axial leaded 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 applica-

tions are in switching power supplies, converters, free-

wheeling diodes, and reverse battery protection.
