B340BQ-13-F Description

Short technical summary and product information.

The B340BQ-13-F is a 40V, 3A Schottky barrier rectifier from Diodes Incorporated, designed for low-voltage, high-frequency applications. It offers a maximum forward voltage of 0.5V at 3A and a reverse leakage current of 0.5mA at rated voltage. The device can handle a peak forward surge current of 125A, making it robust for transient conditions.

This rectifier is housed in a surface-mount DO-214AA (SMB) package with matte tin termination finish. It is RoHS3 compliant, halogen and antimony free, and AEC-Q101 qualified for automotive applications. The operating temperature range is -55°C to 150°C.

Typical applications include polarity protection, freewheeling diodes, and switching power supplies. The guard ring die construction provides transient protection, and the device is suitable for automated assembly.
