Product Description

The onsemi MBRD340T4G is a high-efficiency Schottky barrier rectifier diode designed for low voltage, high-frequency switching and rectification tasks in modern power electronics circuitry. Engineered with a metal barrier to minimize forward voltage drop, this device is ideal for compact power conversion and protection applications where board space and conduction losses are critical factors.

This diode supports a maximum continuous forward current of 3 amperes and a peak repetitive reverse voltage of 40 volts, making it suitable for use in switching power supplies, freewheeling applications, and polarity protection circuits on surface-mount PCBs. With a low maximum forward voltage of 0.7 volts, it ensures minimal power dissipation during operation, contributing to overall system efficiency.

The MBRD340T4G comes in a TO-252 (DPAK) surface-mount package, known for its compact form factor and fast, reliable assembly in automated manufacturing environments. It features a single diode configuration with three pins and is capable of handling non-repetitive forward surge currents up to 75 amperes. The reverse leakage is limited to a peak of 200 microamperes, supporting precise and safe operation.

Its robust construction allows operation in harsh environments, with a wide temperature range from -65°C to 175°C, and it is automotive qualified to the AEC-Q101 standard. The epoxy-molded case further enhances reliability, while the lightweight package makes it suitable for high-density mounting.

The onsemi MBRD340T4G serves vital roles in industrial, commercial, and automotive electronics, including use in power management modules, DC-DC converters, freewheeling diodes in motor drivers, and polarity protection across various embedded and control systems. It is compliant with RoHS standards and is designed for optimal automated board assembly.
