BAS40-04

Diode Arrays Overview

The BAS40-04 is a silicon Schottky barrier diode manufactured by Taiwan Semiconductor Corporation. It features a dual series configuration housed in an SOT-23 surface-mount package. The device is rated for a maximum repetitive peak reverse voltage of 40V and an average rectified forward current of 0.12A. Key electrical characteristics include a low forward voltage drop and minimal reverse leakage current, ensuring efficient performance in small-signal applications.

Diode Arrays Feature Summary

• Dual series-connected Schottky barrier diodes integrated into a single compact component
• Utilizes silicon technology to achieve low forward voltage characteristics
• Designed for surface-mount assembly within the standard SOT-23-3 footprint

Diode Arrays Applications

• Small-signal rectification in consumer electronics
• Signal detection circuits requiring low capacitance and fast switching
• Protection diodes in portable battery-powered devices

Diode Arrays Procurement Notes

Verify the specific manufacturer designation on the datasheet, as BAS40-04 variants exist across multiple vendors including Infineon and NXP. Confirm that the Taiwan Semiconductor version matches the required pinout and thermal specifications for your design. Ensure compliance with RoHS directives if applicable to your region. Cross-reference the ordering suffix to guarantee the correct tape-and-reel quantity and packaging format.

Diode Arrays Selection Notes

Select this component when a dual-diode solution is needed in a minimal footprint. The SOT-23 package offers space efficiency compared to discrete arrangements. Consider the 40V rating and 0.12A current limit against circuit demands. Evaluate the forward voltage drop at expected operating currents to ensure system efficiency meets requirements.

Diode Arrays Part Context

This part belongs to the broader BAS40 family of Schottky diodes, which includes variations like BAS40-05 and BAS40-06. These components share similar physical dimensions but differ in internal configurations, such as common cathode or series connections. The BAS40-04 specifically provides two series-connected elements, distinguishing it from parallel or independent dual-diode options within the same package line.

Diode Arrays Replacement Considerations

Direct substitutes include BAS40-05 and BAS40-06 from compatible manufacturers, provided the pinout and internal topology match the design requirements. Verify that alternative sources offer identical SOT-23 footprints and electrical ratings to ensure seamless integration without schematic modifications.
