onsemi Schottky Diode 40 V 500 mA Surface Mount SOD-123 Package MBR0540T3G

onsemi MBR0540T3G is a Schottky barrier diode designed for surface mount applications requiring high efficiency and compact size. The 40 V max reverse voltage and 500 mA continuous forward current rating make it suitable for low voltage power conversion and protection roles.

The diode uses a Schottky barrier metal contact technology that minimizes forward voltage drop and reverse leakage current, improving overall circuit performance. Its epoxy moulded SOD-123 package offers a lightweight and compact form factor with dimensions of 2.84 mm length, 1.8 mm width, and 1.25 mm height, supporting space-saving PCB layouts and automated manufacturing processes.

This diode withstands transient peak forward surge currents up to 5.5 A and operates reliably across a wide temperature range from -55°C to 150°C. It holds the automotive AEC-Q101 qualification, demonstrating robustness suitable for harsh environmental and automotive electronics applications.

Common uses include high frequency switching power supplies, freewheeling diodes in inductive loads, and polarity protection in various industrial, automotive, and consumer electronic circuits. The device's low voltage drop and fast switching characteristics improve energy efficiency and reduce heat dissipation.

The device is lead-free, RoHS-compliant, and designed for optimal automated board assembly with stress protection features and lightweight packaging weighing approximately 11.7 mg.

Operates with a maximum forward voltage of 610 mV for efficient power use. Single diode configuration suitable for rectification and protection applications. Designed to withstand a peak non-repetitive forward surge current of 5.5 A.
