FEATURES
• 175 °C TJ operation
• Center tap module
• 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
• Through-hole versions are currently available for use in
lead (Pb)-free applications (“PbF” suffix)
• Compliant to RoHS directive 2002/95/EC
• Designed and qualified for industrial level
DESCRIPTION
The center tap Schottky rectifier module 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, converters, freewheeling diodes, and
reverse battery protection.
