BC846S/DG/B2F

Overview

The BC846S/DG/B2F is a dual NPN bipolar junction transistor manufactured by Nexperia. It is housed in a TSSOP-6 (SOT363) surface-mount package. The device supports a maximum collector-emitter voltage of 65 V and a continuous collector current of 100 mA. Key electrical parameters include a collector-base voltage of 80 V, an emitter-base voltage of 6 V, and a power dissipation rating of 300 mW. The component features a transition frequency of 100 MHz and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual NPN configuration with internal isolation for compact circuit designs
• High DC current gain suitable for general-purpose amplification
• Automotive-grade qualification ensuring reliability in demanding environments

Applications

• Current mirror circuits requiring matched transistor characteristics
• Differential amplifier stages in signal processing applications
• General-purpose switching and amplification tasks

Procurement Notes

Verify the specific suffix DG/B2F against official Nexperia documentation to confirm tape-and-reel specifications and manufacturing origin. Confirm RoHS compliance status through the manufacturer's environmental declaration. Ensure the selected distributor provides valid traceability data for automotive-grade components.

Selection Notes

Select this component when a dual NPN topology is required in a minimal footprint SOT363 package. The AEC-Q101 qualification makes it appropriate for automotive electronics where long-term stability is critical. Compare the 300 mW power dissipation limit against thermal requirements in dense PCB layouts.

Part Context

This part belongs to the BC846 series of small-signal transistors. The 'S' designation indicates the dual SOT363 package variant. It serves as a drop-in replacement for standard discrete dual transistors, offering improved matching and reduced board space compared to individual components.

Replacement Considerations

The BCM846BS is a verified substitute within the same family, offering similar dual NPN functionality in the SOT363 package with potentially different gain ranges.
