Product Introduction

Overview

The STPS1L40A, produced by STMicroelectronics, is a single chip Schottky rectifier designed for use in switched mode power supplies and high frequency DC to DC converters. This component is known for its low drop power characteristics, making it ideal for applications requiring minimal conduction losses and negligible switching losses. The STPS1L40A is available in several surface mount packages, including SMA, SMA Flat Notch, SMB, and SOD123Flat, which are ECOPACK2 compliant and meet environmental standards.
