FEATURES
• 150 °C TJ operation
• Center tap configuration
• Very low forward voltage drop
• High frequency operation
Available
RoHS*
COMPLIANT
• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
• Guard ring for enhanced ruggedness and long term
reliability
• Lead (Pb)-free (“PbF” suffix)
• Designed and qualified for Q101 level
DESCRIPTION
This center tap Schottky rectifier 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.
