Overview
The STPS120MF is a single Schottky rectifier produced by STMicroelectronics, designed for use in switch mode power supplies and high frequency DC to DC converters. This device is packaged in the STmite flat package, which is characterized by its very low profile of 0.85 mm. The STPS120MF is backward compatible with the standard STmite footprint, making it a versatile component for various applications. It is particularly suited for low voltage, high frequency inverters, free wheeling, and polarity protection applications. The small size of the package makes it ideal for battery-powered equipment such as cellular devices, notebooks, PDAs, printers, as well as chargers and PCMCIA cards.
