DESCRIPTION PRODUCT SUMMARY
IF(AV) VR 440 A 30 V
The 440CNQ030PBF center tap, high current, Schottky rectifier module has been optimized 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, freewheeling diodes, welding and reverse battery protection.
