Description/ Features
The 8TQ 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, free-wheeling diodes, and reverse
battery protection.
