Integrated in flat and space-saving packages, this STPST5H100 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. ## **Product status link** STPST5H100 |**Product summary**|**Product summary**| |---|---| |**IF(AV)**|5 A| |**VRRM**|100 V| |**Tj (max.)**|175 °C| |**VF (typ.)**|0.550 V| **DS14182** - **Rev 3** - **July 2023** For further information contact your local STMicroelectronics sales office. www.st.com **STPST5H100 Characteristics** ## **1 Characteristics** **Table 1.
