BAV74,215

Overview

The BAV74,215 is a high-speed double diode consisting of two common-cathode switching diodes fabricated in planar technology. It is encapsulated in the SOT23 small Surface-Mounted Device (SMD) plastic package. Key electrical specifications include a maximum continuous reverse voltage of 50 V, a repetitive peak reverse voltage of 60 V, and a repetitive peak forward current of 450 mA. The device exhibits a maximum switching speed of 4 ns. It is qualified to AEC-Q101 standards for automotive applications.

Feature Summary

• High switching speed with a maximum transition time of 4 ns
• Planar technology construction with integrated guard ring for stress protection
• AEC-Q101 qualified for automotive reliability requirements

Applications

• High-speed switching in thick-film circuits
• High-speed switching in thin-film circuits
• General purpose signal switching in compact electronic designs

Procurement Notes

Verify the complete part number including the ordering code suffix to ensure correct packaging configuration. Confirm that the specific variant matches the required AEC-Q101 qualification status if used in automotive contexts. Cross-reference the datasheet revision date to ensure compatibility with current design specifications. Ensure the SOT23 package dimensions align with the target PCB footprint constraints.

Selection Notes

Select this component when dual common-cathode switching functionality is required in a minimal footprint. The SOT23 package offers space efficiency compared to larger discrete diode arrangements. Consider the 4 ns switching speed for high-frequency signal paths. Verify thermal dissipation requirements against the 450 mA forward current rating for the specific circuit application.

Part Context

The BAV74 belongs to Nexperia's portfolio of high-speed switching diodes designed for compact surface-mount applications. It serves as a dual-diode solution replacing two individual components, thereby reducing board space and assembly complexity. The common-cathode configuration simplifies circuit topology for switching and clamping tasks in dense electronic assemblies.

Replacement Considerations

Direct replacements must match the SOT23 package, common-cathode configuration, and AEC-Q101 qualification. Verify that substitute parts maintain the 4 ns switching speed and 50 V reverse voltage ratings. Check for identical pinout assignments to ensure mechanical and electrical compatibility without circuit redesign.
