Overview
The STPS160U is a 60 V, 1 A power Schottky rectifier manufactured by STMicroelectronics. This device is designed for high-frequency miniature switched mode power supplies, such as adaptors and on-board DC/DC converters. It is packaged in SMA (JEDEC DO-214AC) and SMB (JEDEC DO-214AA) surface mount miniature packages, making it ideal for surface mounting applications.
The STPS160U is particularly suited for use in low voltage, high frequency inverters, free wheeling, and polarity protection applications. Its design ensures very small conduction losses, negligible switching losses, and a low forward voltage drop, which are critical for efficient power management in various electronic systems.
