MSS1P4HM3_A/H Description

Short technical summary and product information.

The MSS1P4HM3_A/H is a surface-mount Schottky barrier rectifier diode from Vishay General Semiconductor. It is rated for a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 1 A. The diode exhibits a low forward voltage drop of 0.41 V at 1 A, contributing to high efficiency and reduced power losses. With a peak forward surge current rating of 25 A (8.3 ms single half sine-wave), it can handle high inrush currents. The device is designed for low voltage, high frequency applications such as inverters, freewheeling, DC/DC converters, and polarity protection. It features a very low profile (typical height 0.65 mm) and is ideal for automated placement. The MicroSMP (DO-219AD) package is RoHS-compliant, halogen-free, and meets UL 94 V-0 flammability rating. The HM3 suffix indicates AEC-Q101 qualification for automotive applications.
