15 A
30 V to 45 V
The VS-150SQ... axial leaded Schottky rectifier series has
been optimized for very low forward voltage drop, with
moderate leakage. The proprietary barrier technology allows
for reliable operation up to 150 °C junction temperature.
Typical applications are in switching power supplies,
converters, freewheeling diodes, and reverse battery
protection.
T
J
200 °C for use in solar cell box as a bypass diode for
protection, using DC forward current without reverse bias.
