DESCRIPTION
PRODUCT SUMMARY
IF(AV)
40 A
VR
15 V
This center tap Schottky rectifier has been optimized for very
low forward voltage drop, with moderate leakage. The
proprietary barrier technology allows for reliable operation up
to 125 °C junction temperature. Typical applications are in
switching power supplies, converters, freewheeling diodes,
and reverse battery protection.
