DESCRIPTION
The 10TQ...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.
