MBRD340T4G Description

Short technical summary and product information.

The MBRD340T4G is a Schottky barrier rectifier diode from ON Semiconductor, designed for switch-mode power supply applications. It offers a peak repetitive reverse voltage of 40V and an average rectified forward current of 3A at a case temperature of +125°C. The forward voltage is typically 0.6V at 3A, contributing to high efficiency in low-voltage circuits.

 

This device features extremely fast switching with a recovery time of less than 500ns, making it suitable for freewheeling and protection diodes in inductive switching circuits. It can handle nonrepetitive peak surge currents up to 75A. The junction operating temperature range is -65°C to 175°C.

 

The MBRD340T4G is housed in a DPAK (TO-252) surface mount package, which provides excellent thermal performance with a junction-to-case thermal resistance of 6°C/W. The package is Pb-free, halogen free, and RoHS compliant. Typical applications include output rectification in switching power supplies, inverters, and other inductive switching circuits.
