B290-13

Overview

The B290-13 is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a 90V repetitive peak reverse voltage and a 2.0A average forward rectified current rating. The device utilizes an SMB (DO-214AA) package for compact PCB integration. Key electrical characteristics include a low forward voltage drop to minimize power loss and high surge current capability for robust operation under transient conditions.

Feature Summary

• Schottky barrier construction ensures ultra-fast switching speeds and minimal reverse recovery charge.
• Low forward voltage drop reduces conduction losses and improves overall system efficiency.
• High surge current handling capability provides protection against inrush currents.

Applications

• General-purpose rectification in AC/DC converters
• Free-wheeling diodes in DC/DC converter circuits
• Polarity protection in low-voltage power supply inputs

Procurement Notes

Verify the specific suffix designation, as 'B290' may appear with various trailing characters indicating packaging or tape-and-reel specifications. Confirm that the procurement source explicitly lists the '13' suffix if reel quantity or specific manufacturer lot codes are required for your assembly process. Cross-reference the datasheet revision date to ensure compliance with current RoHS standards.

Selection Notes

Select this component when a fast-switching rectifier is needed for low-to-medium current applications up to 2.0A. The 90V rating suits systems operating below this threshold. Ensure the ambient temperature does not exceed the maximum junction temperature specified in the datasheet. Consider thermal derating factors if the device will operate near its current limits in enclosed spaces.

Part Context

This part belongs to Diodes Incorporated's line of surface mount Schottky rectifiers. It is designed for general-purpose use where speed and efficiency are prioritized over high voltage blocking capabilities. The SMB package allows for automated placement and is suitable for consumer electronics and industrial control boards requiring reliable rectification.

Replacement Considerations

Direct substitutes must match the 2.0A current, 90V voltage, and SMB package constraints. Verify pinout compatibility and thermal resistance values before substitution. Generic equivalents may differ in reverse leakage current or forward voltage characteristics, potentially affecting circuit performance.
