• High frequency operation

• Low forward voltage drop

• 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 6TQ...PbF Schottky rectifier series 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.
