Description
D²PAK
This single rectifier is based on a proprietary technology, enabling to achieve the best
in class VF/IR for a given silicon surface.
Packaged in TO-220AB, TO-220FPAB and D2PAK, the FERD40H100S is optimized
for use in confined applications where both efficiency and thermal performance are
key. With a lower dependency of leakage current (IR) and forward voltage (VF) in
function of temperature, the thermal runaway risk is reduced. It is highly
recommended to be used in adapters and chargers.

To evaluate the conduction losses, use the following equation:
P = 0.420 x IF(AV) + 0.009 x IF2(RMS)
