Overview
The BC850BW-QF is an NPN general-purpose bipolar junction transistor manufactured by Nexperia. It is housed in a SOT-323 (SC-70) surface-mount plastic package. The device features a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. Key electrical parameters include a collector-base voltage of 50 V, an emitter-base voltage of 5 V, and a power dissipation of 200 mW. The component has a minimum DC current gain (hFE) of 200 at 2 mA and 5 V. It operates within a temperature range of -65 °C to +150 °C.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q101 standards for enhanced reliability in vehicle environments.
- Designed for low-noise performance suitable for sensitive signal processing applications.
- Utilizes a compact SOT-323 surface-mount package for efficient PCB space utilization.
Applications
- Low noise stages in audio-frequency equipment
- General purpose switching circuits
- Amplification tasks in consumer electronics
Procurement Notes
Verify the specific suffix 'QF' against official Nexperia documentation to confirm automotive grade status and tape-and-reel packaging details. Ensure the ordering part number matches the exact pinout and marking code required for your assembly process. Cross-reference with authorized distributors to validate authenticity and traceability records.
Selection Notes
Select this component when an NPN transistor with high current gain and low noise characteristics is required in a small form factor. The AEC-Q101 qualification makes it suitable for automotive applications where long-term reliability is critical. Compare hFE ranges and thermal resistance values against alternative devices to ensure compatibility with existing circuit designs.
Part Context
This component belongs to the BC850 series of NPN transistors from Nexperia. It serves as the complement to the PNP BC860 series. The 'Q' suffix typically denotes automotive grade qualification, while 'F' indicates reel packaging. This family is designed for general-purpose switching and amplification in various electronic systems.
Replacement Considerations
Check for direct equivalents such as the BC850B or BC850C if automotive qualification is not strictly required. Verify that any substitute maintains the same SOT-323 footprint and electrical ratings. Confirm pin compatibility before replacing to avoid circuit damage.
