B240A-13-F

Overview

The B240A-13-F is a single Schottky barrier rectifier manufactured by Diodes Incorporated. It features a 40 V repetitive peak reverse voltage (Vrrm) and a 2 A average forward current (If). The device utilizes silicon technology in an SMA (DO-214AC) surface-mount package. Key electrical parameters include a maximum forward voltage of 500 mV at 2 A, a reverse leakage current of 500 µA at 40 V, and a non-repetitive peak forward surge current rating of 50 A. It operates within a temperature range of -65 °C to +150 °C junction temperature.

Feature Summary

• Guard ring die construction provides transient protection capabilities.
• Low forward voltage drop ensures high efficiency and reduced power loss.
• Surge overload rating supports handling of high transient currents.

Applications

• Free wheeling applications in low voltage circuits
• Polarity protection for sensitive electronic loads
• Low voltage, high frequency inverters

Procurement Notes

Verify the specific suffix '13-F' against official Diodes Incorporated documentation to confirm lead-free status and halogen-free compliance. Ensure the SMA (DO-214AC) package matches the target PCB footprint. Cross-reference the datasheet revision date to validate thermal characteristics and absolute maximum ratings before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring efficient rectification at 40 V with moderate current demands up to 2 A. The SMA package suits space-constrained surface-mount assemblies. Consider the 500 mV forward voltage drop for thermal management calculations. Verify that the 50 A surge rating aligns with the circuit's expected inrush or fault conditions.

Part Context

This part belongs to the B220/A through B260/A series of surface mount Schottky rectifiers from Diodes Incorporated. These devices are designed for general-purpose rectification where low forward voltage and fast switching speeds are critical. The series offers various voltage ratings while maintaining consistent package dimensions for design flexibility.

Replacement Considerations

Direct substitutes within the same series include B220A-13-F (20 V), B260A-13-F (60 V), and B280A-13-F (80 V), provided the voltage rating meets the circuit requirements. Other manufacturers offering DO-214AC packaged Schottky diodes with 40 V and 2 A ratings may serve as alternatives if pin compatibility and electrical specs are verified.
