Description
This 10 A, 100 V rectifier is based on ST trench technology that achieves the best-inclass V
F
/I
R
trade-off for a given silicon surface.
Integrated in a DPAK package, this STPST10H100SB 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.
