B540C-13-G

Overview

The B540C-13-G is a silicon Schottky rectifier manufactured by Diodes Incorporated, designed for surface-mount applications. It features a single diode configuration housed in an SMC (DO-214AB) package. The device supports a maximum average forward rectified current of 5 A and a repetitive peak reverse voltage of 40 V. Key electrical characteristics include a low forward voltage drop of 550 mV at rated current and a high non-repetitive peak forward surge current capability of 100 A. The component operates within a temperature range from -55 °C to +125 °C junction temperature.

Feature Summary

• Utilizes Schottky barrier technology to achieve low forward voltage drop and minimize power loss during conduction.
• Engineered with silicon construction to provide robust performance under high thermal stress conditions.
• Features a compact SMC (DO-214AB) surface-mount footprint optimized for automated assembly processes.

Applications

• High-frequency switching power supplies
• Free-wheeling rectification in DC-DC converters
• Reverse polarity protection circuits

Procurement Notes

Verify the specific suffix '-G' against the manufacturer's official documentation to confirm compliance status or material composition differences compared to standard variants. Ensure the selected part number matches the required RoHS directives and lead-free specifications mandated by your project constraints before finalizing procurement orders.

Selection Notes

Select this component when a low forward voltage drop is critical for efficiency in 40 V systems requiring up to 5 A continuous current. The SMC package offers a balance between current handling capacity and board space savings. Verify that the operating environment remains within the specified -55 °C to +125 °C junction temperature range to ensure reliable long-term operation.

Part Context

This component belongs to the B5xxxC series of Schottky rectifiers from Diodes Incorporated, which provides various voltage ratings within the same physical package family. The B540C variant specifically targets 40 V applications, distinguishing it from lower or higher voltage counterparts like the B340C or B640C while maintaining identical thermal and mechanical characteristics.

Replacement Considerations

Compatible substitutes include the B540C-13 and PDS540-13 from Diodes Incorporated, provided pinout and electrical parameters match exactly. Cross-manufacturer replacements must verify identical DO-214AB footprint dimensions and equivalent 5 A/40 V ratings to maintain circuit integrity without redesign.
