BAV74-QR

Overview

The BAV74-QR is an AEC-Q101 qualified high-speed double diode consisting of two switching diodes with common cathodes, fabricated in planar technology. It is encapsulated in a small SOT23 Surface-Mounted Device plastic package. The device supports a continuous reverse voltage of up to 50 V and a repetitive peak reverse voltage of up to 60 V. It handles a repetitive peak forward current of up to 450 mA with a maximum switching speed of 4 ns.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• High-speed switching capability with minimal delay
• Compact SOT23 surface-mount packaging for space-constrained designs

Applications

• High-speed switching in thick-film circuits
• High-speed switching in thin-film circuits

Procurement Notes

Verify the specific suffix indicates automotive qualification status against official Nexperia documentation. Confirm the package type matches design requirements. Ensure the component meets the required temperature range for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when automotive-grade reliability is required alongside high-speed switching performance. The common cathode configuration simplifies circuit layout compared to discrete dual-diode solutions. Verify that the 50 V continuous reverse voltage rating exceeds the maximum expected operating voltage in the target application.

Part Context

The BAV74-QR belongs to Nexperia's portfolio of high-speed switching diodes designed for compact electronic applications. The 'QR' suffix typically denotes automotive qualification under AEC-Q101 standards, distinguishing it from standard commercial variants within the same functional family.

Replacement Considerations

Check for other BAV74 variants with different suffixes that may offer identical electrical characteristics but varying qualification levels or packaging options. Ensure any substitute maintains the SOT23 package and common cathode configuration.
