Overview
The BC857BQB-QZ is a PNP general-purpose transistor manufactured by Nexperia, housed in an ultra-small DFN1412D-3 (SOT8009) leadless surface-mounted device plastic package. It features a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The component is qualified to the AEC-Q101 automotive standard for robust reliability. Key electrical parameters include a collector-base voltage of 50 V, an emitter-base voltage of 5 V, and a total power dissipation of 250 mW. The minimum DC current gain (hFE) is specified at 220.
Feature Summary
- AEC-Q101 qualified for automotive applications
- Ultra-small leadless DFN1412D-3 package design
- Side-wettable flanks for enhanced solder joint inspection
Applications
- General-purpose switching
- Amplification circuits
- Automotive electronics systems
Procurement Notes
Verify the specific suffix QZ against official Nexperia documentation to confirm the exact tape-and-reel quantity and packaging configuration. Ensure the procurement channel provides valid traceability records required for AEC-Q101 qualified components. Confirm that the delivered parts match the DFN1412D-3 package dimensions and side-wettable flank specifications detailed in the datasheet.
Selection Notes
Select this component when a small form factor is critical alongside automotive qualification requirements. The DFN1412D-3 package offers significant board space savings compared to traditional SOT-23 packages while maintaining comparable thermal performance. The side-wettable flanks facilitate automated optical inspection, ensuring higher assembly quality control standards are met during manufacturing.
Part Context
This part belongs to the BC857 series of PNP general-purpose transistors from Nexperia. The series includes various package options such as SOT-23, SC-88, and other DFN variants. The BC857BQB-QZ specifically utilizes the DFN1412D-3 package, distinguishing it from larger footprint alternatives within the same functional family.
Replacement Considerations
Direct substitutes include BC857BQC and BC857CQC, which share the same DFN1412D-3 package and electrical characteristics. Verify pinout compatibility and hFE binning requirements before substitution.
