Battery Isolation Diode

Description Features

The 240NQ045 high current Schottky rectifi er module has been optimised 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, free-wheeling diodes, and reverse battery protection. • 150°C CT

operations• Unique high power, Half-Pak module• Replaces four parallel DO-5’s• Easier to mount and lower profi le than DO-5’s• High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance• Very low forward voltage drop • High frequency operation • Guard ring for enhanced ruggedness and long term reliability
