DESCRIPTION
PRODUCT SUMMARY
IF(AV)
2 x 30 A
VR
35 to 45 V
This center tap Schottky rectifier 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.
