FEATURES

• 150 °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-mould low profile, small footprint, high
current package

• Through-hole versions are currently available for use in
lead (Pb)-free applications (“PbF” suffix)

• Designed and qualified for industrial level

DESCRIPTION

The center tap Schottky rectifier module series 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.
