## **Description** 

This 2 A, 100 V rectifier is based on ST trench technology that achieves the best-inclass VF/IR trade-off for a given silicon surface. 

**Product status link** STPST2H100-Y 

Integrated in flat and space-saving packages, this STPST2H100-Y trench, and automotive-graded device is intended to be used in high frequency miniature switched mode power supplies such as in automotive, DC/DC converters or ECU power supply. It is also adapted to freewheeling applications, OR-ring, or reverse polarity protection.
