B340LB-13

Overview

The B340LB-13 is a single-phase Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface mount applications. It features an SMB (DO-214AA) package and utilizes silicon technology. The device supports a peak repetitive reverse voltage of 40 V and provides an average rectified output current of 3.0 A at a terminal temperature of 90°C. Key electrical parameters include a maximum forward voltage drop of 0.450 V at 3.0 A input current and a non-repetitive peak forward surge current rating of 70 A. The component operates within a junction and storage temperature range of -40 to +125 °C.

Feature Summary

• Guard ring die construction provides transient protection capabilities
• Very low forward voltage drop contributes to high efficiency and reduced power loss
• Ideally suited for automatic assembly processes

Applications

• Low voltage, high frequency inverters
• Free wheeling circuits
• Polarity protection

Procurement Notes

Verify the specific suffix configuration against official documentation to ensure correct packaging and plating specifications. Confirm that the ordering information aligns with the required tape and reel quantities for the SMB package variant. Cross-reference the datasheet revision to validate all mechanical dimensions and electrical characteristics prior to integration into production designs.

Selection Notes

Select this component when a surface mount Schottky rectifier with an SMB footprint is required for 40V applications. Ensure the design accommodates the specified thermal resistance and derating curves for continuous operation. Verify that the 70A surge rating meets the circuit's transient requirements and that the low forward voltage characteristics align with system efficiency targets.

Part Context

This part belongs to the B340LA/B series of low VF Schottky barrier rectifiers from Diodes Incorporated. The 'B' suffix specifically denotes the SMB (DO-214AA) surface mount package, distinguishing it from the SMA package variant. The series is engineered for general-purpose rectification in compact electronic designs requiring high reliability and efficient power conversion.

Replacement Considerations

The B340LA-13 serves as the direct package alternative within the same series, utilizing the SMA footprint instead of SMB. Both variants share identical electrical ratings and functional characteristics. Ensure physical board space constraints dictate the choice between the two package types.
