onsemi 40 V 1 A Surface Mount Schottky Diode 2-Pin SOD-123FL MBR140SFT3G

The onsemi MBR140SFT3G is a high-performance Schottky diode packaged in a compact 2-pin SOD-123FL surface mount form factor. Designed to operate at a maximum continuous forward current of 1 A and withstanding peak reverse voltages up to 40 V, it offers efficient rectification for low voltage power applications.

Manufactured using state-of-the-art epitaxial construction with chrome barrier metal and oxide passivation, this Schottky rectifier exhibits low forward voltage drop of 0.88 V, minimizing power dissipation and improving overall circuit efficiency. Its robust electrical characteristics allow it to function reliably across a wide operating temperature range of -55°C to 125°C, making it suitable for automotive and industrial environments.

The device features a guard ring for stress protection and a package optimized for automated PCB assembly processes. Its peak non-repetitive forward surge current rating of 30 A ensures durability in transient conditions, while its ESD ratings provide resistance against electrostatic discharges.

Typical applications include use as rectifiers in low-voltage, high-frequency inverters, free-wheeling diodes in motor drive circuits, and polarity protection diodes in electronic devices. The MBR140SFT3G’s compact size coupled with compliance to automotive standard AEC-Q101 makes it an excellent choice for use in automotive electronics and demanding industrial control systems.
