Overview
The BC857B-QR is a PNP general-purpose bipolar junction transistor manufactured by Nexperia. It operates within a collector-emitter voltage of 45 V and supports a maximum DC collector current of 100 mA. The device features a minimum DC current gain (hFE) of 220 at 2 mA and 5 V, with a transition frequency of 100 MHz. Packaged in the SOT-23 (TO-236AB) surface-mount format, it dissipates up to 250 mW. Certified under AEC-Q101 for automotive reliability, it functions between -65°C and +150°C.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q101 standards
- High DC current gain ensuring efficient signal amplification
- Robust thermal performance across extended temperature ranges
Applications
- Automotive electronic circuits requiring qualified components
- General-purpose switching applications
- Signal amplification stages
Procurement Notes
Verify the specific suffix 'QR' against official Nexperia documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component meets AEC-Q101 requirements for your target automotive application. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when an automotive-qualified PNP transistor is required for space-constrained designs. The SOT-23 package offers a compact footprint suitable for dense PCB layouts. Consider the 100 mA current limit and 45 V voltage rating to ensure adequate headroom for the intended circuit operation.
Part Context
This part belongs to the BC857 series of small-signal PNP transistors from Nexperia. The series includes variants like BC857A and BC857C with different gain bins. The BC857B-QR specifically targets automotive markets through its AEC-Q101 certification, distinguishing it from standard commercial grade counterparts while maintaining similar electrical characteristics.
Replacement Considerations
Direct substitutes include other AEC-Q101 qualified PNP transistors in SOT-23 packages such as the BC858B-QR or BC857B,215. Verify pinout compatibility and ensure replacement parts meet the same hFE binning and voltage ratings.
