BC847CQAZ

Overview

The BC847CQAZ is a general-purpose NPN bipolar junction transistor manufactured by Nexperia. It features a maximum collector-emitter voltage (VCEO) of 45 V and a continuous DC collector current (IC) of 100 mA. The device utilizes the SOT363 surface-mount package, measuring 2.2 mm in length, 1.2 mm in width, and 1.1 mm in height. Key electrical parameters include a minimum DC current gain (hFE) of 200 at IC = 2 mA and VCE = 5 V, and a transition frequency (fT) of 100 MHz. The component operates within a temperature range of -65°C to +150°C and has a total power dissipation of 200 mW.

Feature Summary

• High DC current gain selection for efficient signal amplification
• Ultra-small footprint suitable for space-constrained designs
• Low collector capacitance for improved switching performance

Applications

• General-purpose switching circuits
• Small-signal amplification stages
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix 'QAZ' against official Nexperia documentation to confirm it denotes automotive qualification or specific tape-and-reel packaging standards. Ensure the ordering part number matches the exact pinout and gain binning required for the design. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a high-gain NPN transistor is required in a compact SMD package. The BC847C variant provides a higher hFE range compared to A or B variants, making it suitable for applications demanding greater sensitivity. Consider the 200 mW power dissipation limit and thermal management requirements for the SOT363 package during PCB layout planning.

Part Context

This component belongs to the BC847 series of general-purpose NPN transistors from Nexperia. The series offers various gain selections (A, B, C) and complementary PNP types (BC857). The BC847CQAZ specifically integrates the C gain bin into an automotive-grade or specialized packaging configuration, maintaining the standard electrical characteristics of the broader BC847 family while potentially adhering to stricter quality or reliability standards.

Replacement Considerations

Direct substitutes include other BC847C variants such as BC847C,115 or BC847C,215, provided the packaging and suffix specifications align with the design requirements. Verify that any replacement maintains the same SOT363 footprint and electrical ratings.
