MBRD340G

MBRD340G Description

The MBRD340G from onsemi is a high-performance Schottky diode designed for fast-switching and power-efficient applications. Part of the SWITCHMODE™ series, it features a low forward voltage drop (600 mV max @ 3 A) and ultra-fast recovery time (≤500 ns), making it ideal for high-frequency rectification. With a 40 V reverse voltage rating and 3 A average rectified current, this surface-mount diode is optimized for compact, high-efficiency designs. Packaged in a DPAK (TO-252) form factor, it is RoHS3 compliant and suitable for automated assembly processes.

MBRD340G Features

• Low V_F & Fast Recovery: Minimizes power loss and improves efficiency in switching circuits.
• High Current Handling: Supports 3 A continuous current with 200 µA max reverse leakage at 40 V.
• Robust Construction: Schottky technology ensures reliability under high-temperature conditions.
• Surface-Mount DPAK Package: Space-saving and compatible with reflow soldering (MSL 1).
• Compliance: Meets ROHS3 and REACH standards, with EAR99 export classification.

MBRD340G Applications

• Switch-Mode Power Supplies (SMPS): Enhances efficiency in DC-DC converters and voltage regulators.
• Reverse Polarity Protection: Low V_F reduces voltage drop in battery-powered systems.
• High-Frequency Rectification: Ideal for freewheeling diodes in motor drives and inductive load clamping.
• Solar & Automotive Systems: Suitable for photovoltaic bypass diodes and 12V/24V automotive circuits.

Conclusion of MBRD340G

The MBRD340G stands out for its fast recovery, low forward voltage, and high current capability, making it a superior choice for modern power electronics. Its DPAK package and compliance with environmental standards ensure compatibility with industrial and consumer applications. While marked as obsolete, it remains a reliable option for designs prioritizing efficiency and compactness.
