MBRD340RLG

MBRD340RLG Description

The MBRD340RLG is a Schottky barrier rectifier from onsemi's SWITCHMODE™ series, designed for high-efficiency power applications. This surface-mount diode features a 40V reverse voltage (Vr) and 3A average forward current (Io), making it suitable for high-current, fast-switching circuits. Its Schottky technology ensures low forward voltage drop (600mV max @ 3A) and ultra-fast recovery (<500ns), minimizing power losses and improving thermal performance. Packaged in a DPAK (TO-252) format with Tape & Reel (TR) delivery, it is optimized for automated assembly.

MBRD340RLG Features

• Low Vf & Fast Recovery: Reduces conduction losses and enhances efficiency in high-frequency circuits.
• High Current Handling: Supports 3A continuous current, ideal for power supply and motor drive applications.
• Surface-Mount DPAK Package: Compact, thermally efficient, and compatible with PCB automation.
• RoHS3 & REACH Compliant: Meets environmental standards for global use.
• Low Reverse Leakage (200µA @ 40V): Improves system reliability in precision applications.
• Wide Operating Range: Suitable for switching power supplies, DC-DC converters, and reverse polarity protection.

MBRD340RLG Applications

• Switch-Mode Power Supplies (SMPS): Enhances efficiency in AC-DC and DC-DC converters.
• Motor Drives & Inverters: Low Vf minimizes heat generation in PWM-controlled systems.
• Solar Power Systems: Optimizes performance in bypass diodes and MPPT trackers.
