Schottky Rectifier, 10 A

FEATURES

• 175 °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 10TQ... 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.
