PRODUCT SUMMARY
IF(AV) VR 2 x 10 A 35 to 45 V

The 20CTQ.. center tap 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.
