B240LA-13-F

Overview

The B240LA-13-F is a surface-mount Schottky barrier rectifier manufactured by Diodes Incorporated. It features a single diode configuration housed in an SMA (DO-214AC) package with two pins. The device supports a maximum average forward rectified current of 3 A and a repetitive peak reverse voltage of 40 V. Key electrical parameters include a maximum forward voltage of 450 mV at 3 A, a peak non-repetitive forward surge current of 70 A, and a maximum reverse current of 2 mA. The component operates within a temperature range from -55°C to +125°C.

Feature Summary

• Guard ring die construction provides protection against transient voltage events.
• Low forward voltage drop minimizes power loss and enhances overall circuit efficiency.
• Designed for automated assembly processes using standard surface-mount techniques.

Applications

• Free-wheeling rectification in low-voltage DC circuits
• Polarity protection for sensitive electronic loads
• High-frequency inverters requiring fast switching characteristics

Procurement Notes

Verify the specific suffix '13-F' confirms lead-free finish and RoHS compliance status. Confirm the SMA (DO-214AC) package matches the target PCB footprint. Ensure the 40 V rating aligns with the system's peak inverse voltage requirements. Check for any recent Product Change Notifications that may affect material composition or manufacturing location.

Selection Notes

Select this component when a 3 A current capacity and 40 V blocking voltage are required in a compact SMA package. Compare the 450 mV forward voltage against alternatives if lower conduction losses are critical. Consider the 70 A surge rating for applications with high inrush currents. Verify thermal management needs given the 125°C junction temperature limit.

Part Context

This part belongs to the B240LA series of Schottky rectifiers from Diodes Incorporated. It shares the same electrical specifications as the B240A-13-F but utilizes the SMA (DO-214AC) surface-mount package instead of axial leads. The series is designed for general-purpose rectification where low forward voltage and high efficiency are prioritized over high voltage blocking capabilities.

Replacement Considerations

The B240A-13-F is a direct pin-compatible alternative with identical electrical ratings but in a different package style. For surface-mount replacements, verify that any substitute maintains the 3 A current rating and 40 V reverse voltage while fitting the SMA footprint.
