Vishay V40DM45CM3I Dual Schottky Rectifier

The V40DM45C is a dual low-voltage trench MOS barrier Schottky rectifier designed for high efficiency in power conversion applications. This component features ultra-low forward voltage drop of 0.34 V at 5 A, reducing power losses in high-frequency DC/DC converters, switching power supplies, and reverse battery protection systems. It is RoHS compliant, halogen-free, and meets industry standards including UL 94 V-0 flammability rating and J-STD-020 MSL level 1. The compact SMPD (TO-263AC) package allows for automated placement, supporting automotive, industrial, and commercial uses with a maximum junction temperature of 175°C and high surge current capabilities.
