DESCRIPTION
The NKSD300... Schottky rectifier common
cathode module 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 high
current switching power supplies, plating
power supplies, UPS systems, converters,
freewheeling diodes, welding, and reverse
battery protection.
