PRODUCT SUMMARY
IF(AV) |
2 x 6 A |
VR |
35 to 45 V |
DESCRIPTION
The 12CTQ... 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.
