Schottky Rectifier, 9 A

90SQ... Series

Vishay High Power Products

FEATURES

• Low forward voltage drop

• High frequency operation

• High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

• Guard ring for enhanced ruggedness and long term

reliability

• Lead (Pb)-free plating

• Designed and qualified for industrial level

DESCRIPTION

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

applications are in switching power supplies, converters,

freewheeling diodes, and reverse battery protection.
