Overview
The Diotec Semiconductor BC846AW is a small-signal NPN bipolar junction transistor housed in an SOT-323 surface-mount package. It features a maximum collector-emitter voltage (VCEO) of 65 V and a continuous DC collector current (IC) rating of 100 mA. The device provides a typical power dissipation (Ptot) of 200 mW at 25°C ambient temperature, increasing to 225 mW when mounted on a PCB with 3 mm² copper pads. It operates within a junction temperature range of -55°C to +150°C and includes three distinct DC current gain groups.
Feature Summary
- Offers three selectable DC current gain groups for precise amplification control
- Compliant with RoHS directives without exemptions and REACH regulations
- Designed for general-purpose signal processing, switching, and amplification tasks
Applications
- Signal processing circuits
- Electronic switching applications
- General-purpose amplification stages
Procurement Notes
Verify the specific ordering suffix against official Diotec documentation to confirm the exact electrical characteristics and compliance grade. Confirm that the component meets all necessary environmental standards required for your specific application before finalizing procurement decisions.
Selection Notes
Select this component based on its 65 V collector-emitter breakdown voltage and 100 mA current handling capability. Ensure the chosen current gain group aligns with the circuit's amplification requirements. Verify thermal management needs relative to the 200 mW power dissipation limit under expected operating conditions.
Part Context
This part belongs to the BC846W series of SMD universal NPN transistors manufactured by Diotec Semiconductor. It is designed as a standard commercial/industrial grade component intended for general electronic applications requiring reliable small-signal performance in compact surface-mount form factors.

FAQ
What are the minimum DC current gain values for the BC846AW?
At IC = 2 mA and VCE = 5 V, the minimum hFE values are 110 for Group A, 200 for Group B, and 420 for Group C.
How does mounting affect the power dissipation rating?
The standard power dissipation is 200 mW at TA = 25°C. When mounted on a PCB with 3 mm² copper pads at each terminal, it increases to 225 mW.
Is the BC846AW compliant with automotive standards?
No, the BC846AW is a commercial/industrial grade component. Automotive-grade versions require specific suffixes such as -Q or -AQ indicating AEC-Q101 compliance or qualification.
