Schottky Rectifier, 9 A
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
• Compliant to RoHS Directive 2002/95/EC
• Designed and qualified for commercial level

(-M3 only)
DESCRIPTION
The VS-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.
