Overview

The MBRS240LT3G is a 2.0 Amp, 40 Volt Schottky Power Rectifier housed in the industry-standard SMB surface-mount package. It is designed for low-voltage, high-frequency rectification and freewheeling applications where high efficiency and small footprint are critical requirements.

Why Choose This Part

The device features an exceptionally low forward voltage of approximately 0.43V at 2A, which significantly reduces power loss and heat dissipation. Its SMB package offers a compact footprint with high thermal performance, and the guard-ring construction provides reliable stress protection against overvoltage transients.

Applications

DC-DC Converters
Used as a catch diode in buck converters or as an output rectifier in boost converters to maximize efficiency through low forward voltage drop.
Reverse Polarity Protection
Protects sensitive downstream circuitry from battery reversal or incorrect power supply polarity in handheld and portable devices.
Freewheeling Diode
Dissipates energy stored in inductive loads such as small motors and solenoid coils to prevent voltage spikes.
Low-Voltage Rectification
Provides rectification in low-power AC-DC adapters and secondary side power management.

Getting Started

When integrating this diode, ensure the PCB trace widths can handle the 2A continuous current and provide adequate copper area for thermal dissipation. For high-speed switching, keep the loop area small between the diode and the power switch to minimize EMI and parasitic inductance.
