BC847C-QR

Overview

The BC847C-QR is an NPN general-purpose transistor from Nexperia, qualified according to AEC-Q101 for automotive applications. It features a maximum collector-emitter voltage (VCEO) of 45 V and a continuous DC collector current (IC) of 100 mA. The device utilizes a SOT-23 (TO-236AB) surface-mount package with dimensions of 3 mm x 1.4 mm x 1.1 mm. Key electrical parameters include a collector-base voltage (VCBO) of 50 V, an emitter-base voltage (VEBO) of 6 V, and a transition frequency (fT) of 100 MHz. The minimum DC current gain (hFE) is specified at 200 under test conditions of IC = 2 mA and VCE = 5 V. Power dissipation is rated at 250 mW, with an operating temperature range from -65 °C to +150 °C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards
• High DC current gain selection (C grade) for sensitive amplification
• Compact SOT-23 surface-mount package for space-constrained designs

Applications

• General-purpose switching in automotive electronic modules
• Signal amplification in low-power audio or sensor circuits
• Driver stages for LED indicators and logic level shifting

Procurement Notes

Verify the specific suffix 'QR' corresponds to the intended reel packaging configuration, as Nexperia utilizes distinct codes for tape-and-reel quantities. Confirm that the AEC-Q101 qualification status meets the specific reliability requirements of the target automotive application tier. Ensure compatibility with standard SMT reflow profiles defined for the SOT-23 package variant.

Selection Notes

Select this component when a high-gain NPN transistor is required for automotive environments. The C-selection offers superior current gain compared to A or B grades, reducing base drive requirements. Compare against the BC847B-QR if lower gain tolerance is acceptable, or the BC847A-QR for cost optimization where higher gain is not critical. Ensure the 45 V rating suffices for the maximum circuit voltage.

Part Context

This part belongs to the BC847x-Q series, which extends the popular BC847 general-purpose transistor family into the automotive sector. The series provides matched performance across different gain bins (A, B, C) within the same small SOT-23 footprint. It serves as a direct replacement for non-qualified BC847C devices in designs requiring enhanced reliability and longevity support under Nexperia's Longevity Program.

Replacement Considerations

Direct pin-compatible substitutes include the BC847B-QR and BC847A-QR, though their current gain specifications differ significantly. Non-automotive equivalents like the standard BC847C may be used if AEC-Q101 qualification is not mandatory.
