FERD20S100S
100 V field-effect rectifier diode
Datasheet - production data
Description
A
The device is based on a proprietary technology
that achieves the best in class VF/IR trade-off for a
given silicon surface. This 100 V rectifier has
been optimized for use in confined casing
applications where both efficiency and thermal
performance matter. With a lower dependency of
leakage current (IR) and forward voltage (VF) in
function of temperature, the thermal runaway risk
is reduced. Therefore, it can advantageously
replace 100 V Schottky diodes.
