Description/Features
The 6TQ 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.
175° C TJ operation
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
Low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
