FEATURES
• 150 °C T_J operation
• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
• High frequency operation
• Low forward voltage drop
• Guard ring for enhanced ruggedness and long term
reliability
• Designed and qualified for industrial level
DESCRIPTION
The MBR7.. Schottky rectifier has been optimized for low
reverse leakage at high temperature. 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.
