B240-13

Overview

The B240-13 is a surface mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a 40V peak repetitive reverse voltage and a 2.0A average rectified output current. The device utilizes an SMB (DO-214AA) case configuration with lead-free matte tin terminals. Electrical characteristics include a maximum forward voltage drop of 0.70V at 2.0A and a leakage current of up to 20mA at rated voltage and 100°C. It supports a non-repetitive peak forward surge current of 50A and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Guard ring die construction provides transient protection capabilities.
• Low power loss design ensures high efficiency in operation.
• Surge overload rating accommodates peak currents up to 50A.
• High-temperature soldering capability allows processing at +260°C for 10 seconds.

Applications

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

Procurement Notes

Verify the specific package type required for the application, as the B240 series includes both SMA and SMB variants. Confirm that the standard B240-13 designation corresponds to the SMB package with 3,000 units per tape and reel. Ensure compliance with RoHS directives and check for AEC-Q101 qualification if automotive reliability standards are necessary for the project.

Selection Notes

Select this component for designs requiring a 40V blocking voltage and 2A continuous current handling in a surface mount format. Consider the thermal resistance values of 20°C/W for the SMB package when calculating heat dissipation. Evaluate the forward voltage drop against system efficiency requirements and ensure the operating temperature range aligns with the environmental conditions of the intended deployment.

Part Context

This part belongs to the B220/A through B260/A family of 2.0A surface mount Schottky barrier rectifiers. The family shares identical mechanical data and electrical performance profiles, differentiated primarily by their peak repetitive reverse voltage ratings ranging from 20V to 60V. The B240 variant specifically addresses applications needing a 40V rating.

Replacement Considerations

Direct substitutes within the same family include B220-13-F, B230-13-F, B250-13-F, and B260-13-F, which share the SMB package and 2.0A current rating but offer different voltage ratings. Automotive-grade equivalents such as B240Q-13-F provide AEC-Q101 qualification while maintaining identical electrical specifications.
