BC846BHE3-TP

Overview

The BC846BHE3-TP is a silicon NPN single bipolar junction transistor manufactured by Micro Commercial Components. It operates within a collector-emitter voltage of 65 V and a collector-base voltage of 80 V, with an emitter-base voltage rating of 6 V. The device supports a maximum continuous DC collector current of 100 mA and dissipates up to 225 mW of power. Key electrical characteristics include a transition frequency of 100 MHz and a DC current gain ranging from 200 to 450 at specified test conditions. It functions reliably between -55°C and +150°C junction temperature.

Feature Summary

• AEC-Q101 qualified for automotive electronics reliability standards
• High DC current gain range (hFE 200-450) for signal amplification
• Low saturation voltage for efficient switching performance
• Surface-mount SOT-23-3 package for compact circuit integration

Applications

• Automotive general-purpose switching circuits
• General-purpose amplifier stages
• Switching applications in consumer electronics
• Signal processing in low-power systems

Procurement Notes

Verify the specific suffix HE3-TP against official MCC documentation to confirm AEC-Q101 qualification status, as standard BC846B variants may lack this certification. Ensure the ordering part number matches the required gain bin (B series) and package type. Cross-reference datasheets directly with the manufacturer to validate RoHS compliance and lead times, as distributor listings may not reflect real-time production constraints or regional availability restrictions.

Selection Notes

Select this component when automotive-grade reliability is required alongside standard NPN switching capabilities. The B-series gain bin provides consistent amplification factors suitable for precision analog tasks. Compare thermal dissipation limits against PCB copper area constraints. Verify that the 100 mA current rating exceeds peak load requirements. Consider the SOT-23-3 footprint compatibility during layout design to ensure seamless replacement in existing designs.

Part Context

This part belongs to the BC846 family of small-signal NPN transistors produced by Micro Commercial Components. The HE3-TP designation indicates a specific manufacturing lot or variant optimized for automotive applications under AEC-Q101 standards. It shares the fundamental electrical profile of the BC846B but includes enhanced quality controls for harsh environments. The component serves as a direct replacement for industry-standard BC846B devices where automotive certification is mandatory.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified BC846B variants from different manufacturers such as ON Semiconductor or Nexperia. Verify pinout compatibility and thermal resistance values before substitution. Generic BC846B parts without the HE3-TP suffix may lack automotive qualification.
