Overview
The BC847A-QR is an NPN general-purpose bipolar junction transistor manufactured by Nexperia. It operates with a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device features a DC current gain (hFE) range of 110 to 800 at 2 mA and 5 V. It is housed in a TO-236AB (SOT-23) surface-mount package with a power dissipation rating of 250 mW. The component meets AEC-Q101 automotive qualification standards and supports operating temperatures from -65 °C to +150 °C.
Feature Summary
- Automotive-grade reliability certified under the AEC-Q101 standard for robust performance in demanding environments.
- High DC current gain selection providing precise amplification characteristics for signal processing applications.
- Compact SMD plastic packaging designed for efficient automated assembly and space-constrained circuit board layouts.
Applications
- General-purpose switching circuits requiring reliable on/off control.
- Small-signal amplification in audio and RF stages.
- Driver stages for logic interfaces and sensor conditioning.
Procurement Notes
Verify the specific suffix 'QR' corresponds to the intended reel or cut-tape packaging configuration required for your manufacturing line. Confirm that the AEC-Q101 qualification aligns with your project's automotive grade requirements. Ensure the TO-236AB footprint matches your PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when high current gain is necessary for low-base-current drive applications. The AEC-Q101 certification makes it suitable for automotive electronics where long-term reliability is critical. Compare the 100 mA limit against load requirements to ensure safe operation within the specified thermal boundaries.
Part Context
This part belongs to the BC847 series of NPN transistors, which are widely used as standard general-purpose devices. The 'A' designation indicates a specific binning for current gain, while the '-QR' suffix typically denotes automotive-grade packaging and traceability. It serves as a complement to the PNP BC857A variant in push-pull configurations.
Replacement Considerations
Direct substitutes include the BC847B-QR and BC847C-QR for different gain requirements. Non-automotive equivalents like the BC847AW,115 may be considered if AEC-Q101 compliance is not mandatory.
