FEATURES
- 150 °C TJ operation 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 Designed and qualified for industrial level
DESCRIPTION
The 20TQ... Schottky rectifier 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.
