BC847CM-QYL

Overview

The BC847CM-QYL is an NPN general-purpose transistor from Nexperia, designed for surface-mount applications. It operates with a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device utilizes the SOT323 (SC-70) plastic package, measuring 2 x 1.25 x 0.95 mm. It is qualified according to AEC-Q101 standards for automotive use. The 'C' suffix indicates a specific DC current gain selection group, typically ranging from 420 to 800 at 2 mA and 5 V. The component supports a maximum junction temperature of 150°C and features a power dissipation rating suitable for compact designs.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards
• High DC current gain selection for precise amplification control
• Ultra-small SC-70 surface-mount package for space-constrained layouts

Applications

• General-purpose switching in automotive electronic modules
• Signal amplification in low-power consumer circuits
• Level shifting and buffering in digital logic interfaces

Procurement Notes

Verify the exact gain binning associated with the 'CM' suffix against the latest official datasheet revision, as gain ranges can vary between manufacturing batches. Confirm the specific packaging variant (tape and reel specifications) matches your automated assembly requirements. Ensure the AEC-Q101 qualification status is explicitly stated for the intended automotive application grade. Cross-reference the ordering code with the manufacturer's current availability list to avoid obsolete stock.

Selection Notes

Select this component when a small form factor is required alongside automotive reliability standards. The high gain range makes it suitable for sensitive signal processing tasks where base current minimization is critical. Compare thermal performance against larger packages if high power dissipation is anticipated. Consider the PNP complement BC857CM-QYL for complementary circuit designs requiring matched characteristics.

Part Context

This part belongs to the BC847xW-Q series, which provides NPN general-purpose transistors in the SOT323 package. The series includes variants with different gain selections (A, B, C) to accommodate various circuit requirements. These devices are widely used in portable electronics and automotive systems due to their small size and robust electrical characteristics. The Q-series designation specifically denotes automotive qualification.

Replacement Considerations

Direct substitutes include other BC847C variants in the SOT323 package from Nexperia or equivalent parts from manufacturers like ON Semiconductor and Diodes Inc., provided they meet the 45V/100mA ratings and AEC-Q101 requirements. Verify pinout compatibility and thermal resistance values before substitution.
