Product Introduction

Overview

The STPS140UY is a 40 V, 1 A power Schottky rectifier produced by STMicroelectronics. This device is part of the STPS140 series, which includes single chip Schottky rectifiers designed for switched mode power supplies and high frequency DC to DC converters. The STPS140UY is packaged in the SMB (Surface Mount Device) format, making it ideal for surface mounting and use in low voltage, high frequency inverters, free-wheeling, and polarity protection applications, particularly in automotive contexts.
