Description
This 1 A, 100 V rectifier is based on ST trench technology that achieves the best-inclass
VF/IR trade-off for a given silicon surface.
Integrated in flat and space-saving packages, this STPST1H100 trench rectifier is
intended to be used in high frequency miniature switched mode power supplies. It
is also an ideal candidate for auxiliary power supply in telecom, server, or smart
metering. ST trench rectifiers are adapted to freewheeling, OR-ring or reverse
polarity protection applications, and can be the perfect companion device to our
transistors, drivers, or ST VIPer products.
