Overview
The BC846BW RFG is an NPN bipolar junction transistor manufactured by Taiwan Semiconductor Corporation. It features a maximum collector-emitter voltage of 65 V and a continuous collector current rating of 100 mA. The device operates with a power dissipation of 200 mW and exhibits a transition frequency of 100 MHz. It is housed in a surface-mount SOT-323 package. The component meets AEC-Q101 automotive qualification standards and supports a junction temperature range from -55°C to +150°C.
Feature Summary
- Automotive-grade reliability certified under AEC-Q101 standards for robust performance in demanding environments.
- High DC current gain of 200 minimum at specified test conditions, ensuring efficient signal amplification.
- Compact SOT-323 surface-mount packaging designed for space-constrained circuit board layouts.
Applications
- General-purpose switching circuits requiring small-signal control.
- Amplifier stages in audio or RF signal processing applications.
- Driver circuits for low-power loads in automotive electronic systems.
Procurement Notes
Verify the complete part number including the RFG suffix against official manufacturer documentation to ensure correct packaging and binning specifications. Confirm that the received components match the AEC-Q101 qualification status required for your specific application. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions prior to final design integration.
Selection Notes
Select this component when automotive qualification is mandatory for NPN switching applications. The 65 V breakdown voltage suits low-voltage digital logic interfaces. Compare the 100 mA current limit against load requirements to prevent thermal overload. Ensure the SOT-323 footprint aligns with existing PCB silkscreen and copper pad designs for proper soldering compatibility.
Part Context
This transistor belongs to the BC846 series of small-signal NPN devices. The series is widely used in consumer electronics and industrial controls. The BC846B variant specifically offers mid-range current gain compared to other binning options within the same family. It serves as a standard replacement for legacy general-purpose transistors in modern compact designs.
Replacement Considerations
Cross-reference with BC846BW variants from other manufacturers such as Diotec or Panjit. Verify pinout compatibility and electrical parameter tolerances before substitution. Ensure alternative parts meet the same AEC-Q101 automotive grade if applicable to the original design intent.
