FEATURES
• 175 °C TJ operation
• Center tap module
• Very 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
• New fully transfer-mold low profile, small footprint, high
current package
• Designed and qualified for industrial level
DESCRIPTION
The center tap Schottky rectifier module has been optimized
for very low forward voltage drop, with moderate leakage.
The proprietary barrier technology allows for reliable
operation up to 175 °C junction temperature. Typical
applications are in switching power supplies, converters,
freewheeling diodes, and reverse battery protection.
