B120-13-F-2477

Overview

The B120-13-F-2477 is a Schottky barrier rectifier manufactured by Diodes Incorporated. It features a maximum average forward rectified current of 1A and a maximum repetitive peak reverse voltage of 20V. The device utilizes Schottky technology to ensure low forward voltage drop and high switching efficiency. It is housed in an SMA surface-mount package, designed for compact circuit board layouts. The component operates within a specified temperature range suitable for general electronic applications.

Feature Summary

• Schottky barrier construction for low forward voltage and fast switching
• Surface-mount SMA package for automated assembly
• Designed for polarity protection and DC-DC converter applications

Applications

• Polarity protection circuits
• Free-wheeling diodes in DC-DC converters
• General purpose rectification in low voltage systems

Procurement Notes

Verify the specific suffix -2477 against official Diodes Incorporated documentation to confirm it denotes the SMA bulk or tape-and-reel packaging variant rather than a functional difference. Ensure the part number matches the exact datasheet revision required for your design. Cross-reference with authorized distributors to confirm availability status, as this specific suffix may indicate end-of-life or last-time-buy status according to some listings.

Selection Notes

Select this component when a low-cost, 1A Schottky rectifier with a 20V rating is required in an SMA footprint. Compare its forward voltage characteristics against competitors if thermal management is critical. Confirm that the 20V reverse voltage provides sufficient margin for your circuit's peak inverse voltage. Verify package compatibility with your PCB footprint before finalizing the selection.

Part Context

This part belongs to Diodes Incorporated's standard Schottky rectifier lineup. The B120 series typically offers 1A current ratings with various voltage options. The -13-F suffix generally indicates RoHS compliance and lead-free finish. The -2477 suffix likely specifies the specific packaging configuration or distributor code, distinguishing it from other variants like the standard B120-13-F.

Replacement Considerations

Direct replacements include the B120-13-F from Diodes Incorporated, ensuring identical electrical specifications and package type. Other manufacturers offering 1A, 20V Schottky diodes in SMA packages may serve as alternatives, provided their forward voltage and reverse leakage current parameters meet the original design requirements.
