Schottky Rectifier, 9 A
90SQ... Series
Vishay High Power Products
FEATURES
• 150 °C TJ operation
• 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.
