DESCRIPTION
PRODUCT SUMMARY
IF(AV)
8A
VR
30/35/40/45 V
The 80SQ axial leaded 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.
