Overview
The STPS30H100CW is a high-voltage power Schottky rectifier produced by STMicroelectronics. This dual Schottky rectifier is designed for high-frequency miniature switch-mode power supplies, such as adaptors and on-board DC-DC converters. It is optimized for use in high-frequency inverters and is available in the TO-247 package.
The device is characterized by its negligible switching losses, low leakage current, and a good trade-off between leakage current and forward voltage drop. It is also avalanche rated and compliant with ECOPACK®2 environmental standards.
