Overview

The B240-13-F is a 2A, 40V Schottky barrier rectifier housed in a surface-mount SMB package. It features a guard ring die construction for transient protection and offers low power loss with high efficiency for power management tasks. This diode is designed for high-reliability applications, including those requiring AEC-Q101 qualification standards.

Why Choose This Part

The component provides a high surge overload rating of up to 50A peak and a low reverse leakage current of 500 uA at 40V. Its SMB package is ideally suited for automated assembly, and the Schottky technology ensures fast recovery times for efficient high-frequency switching.

Applications

Freewheeling Diode
Used in inductive load switching circuits such as DC-DC converters and motor drivers to provide a path for flyback current.
Polarity Protection
Protects sensitive downstream circuitry from damage caused by accidental battery or power supply reversal.
Secondary Rectification
Ideal for use in low-voltage, high-frequency inverters and switch-mode power supplies (SMPS).
ORing Diode
Enables redundant power supply configurations by combining multiple DC voltage sources while preventing back-feeding.
