MBR540MFST1G Description

Short technical summary and product information.

The MBR540MFST1G is a Schottky barrier rectifier from onsemi designed for switch-mode power supply applications. It features a peak repetitive reverse voltage of 40V and an average rectified forward current of 5A. The device offers low forward voltage of 0.50V typical at 5A and 25°C, contributing to high efficiency and low power loss.

 

This rectifier is housed in a surface mount SO-8 FL (Case 488AA) package with 100% matte tin lead finish. It supports an operating junction temperature range of -40°C to 175°C and is rated for MSL 1 moisture sensitivity. The part is Pb-Free and Halide-Free, RoHS3 compliant.

 

Typical applications include output rectification in DC-DC converters, freewheeling diodes, and polarity protection circuits. The guardring design provides stress protection, and the package allows inspection and probing after board mounting.
