FEATURES
• 175 °C T_J operation
• Center tap configuration
• Low forward voltage drop
• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
• High frequency operation
• Guard ring for enhanced ruggedness and long term
reliability
• Designed and qualified for AEC-Q101 level
DESCRIPTION
This center tap Schottky rectifier series has been optimized
for low reverse leakage at high temperature. The proprietary
barrier technology allows for reliable operation up to 175 °C
junction temperature. Typical applications are in switching
power supplies, freewheeling diodes, and reverse battery
protection.
