• Center tap TO-247 package
• 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
• Lead (Pb)-free (“PbF” suffix)
• Designed and qualified for industrial level
DESCRIPTION
The 72CPQ030PbF 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 150 °C junction temperature. Typical
applications are in switching power supplies, converters,
freewheeling diodes, and reverse battery protection.
