PRODUCT SUMMARY
IF(AV) VR 2 x 40 A 35 V to 45 V
The center tap Schottky rectifier module 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.
