FEATURES
• 150 °C TJ operation
• Optimized for 3.3 V application
• Ultralow forward voltage drop
• High frequency operation
• Guard ring for enhanced ruggedness and long
term reliability
• High purity, high temperature epoxy
encapsulation for enhanced mechanical
strength and moisture resistance
• Compliant to RoHS Directive 2002/95/EC

(-N3 only)
DESCRIPTION
This center tap Schottky rectifier has been optimized for
ultralow forward voltage drop specifically for 3.3 V output
power supplies. The proprietary barrier technology allows for
reliable operation up to 150 °C junction temperature. Typical
applications are in switching power supplies, converters,
reverse battery protection, and redundant power
subsystems.
