BC847BQAZ

Overview

The BC847BQAZ is an NPN general-purpose bipolar junction transistor manufactured by Nexperia. It is housed in a compact SOT1215 (DFN1010D-3) surface-mount package with a 3-XDFN footprint and exposed pad. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of 45 V. Key electrical characteristics include a DC current gain (hFE) minimum of 200 at 2 mA and 5 V, a saturation voltage of 400 mV at 5 mA base and 100 mA collector, and a transition frequency of 100 MHz. Maximum power dissipation is rated at 280 mW, with a maximum junction temperature of 150°C.

Feature Summary

• General-purpose switching and amplification capabilities
• Compact DFN1010D-3 surface-mount package design
• High DC current gain selection for signal processing

Applications

• General-purpose switching circuits
• Amplifier stages
• Signal conditioning applications

Procurement Notes

Verify the specific suffix QAZ against official Nexperia documentation to confirm the exact tape-and-reel packaging configuration and quantity per reel. Ensure the ordering part number matches the required DFN1010D-3 package variant. Confirm RoHS compliance status through the manufacturer's latest product compliance declaration before finalizing procurement specifications.

Selection Notes

Select this component when a small form factor NPN transistor is required for space-constrained designs. The BC847BQAZ offers a balance of moderate current handling and high gain suitable for low-power signal applications. Compare the 280 mW power dissipation rating against thermal constraints in the target PCB layout to ensure reliable operation under expected load conditions.

Part Context

This component belongs to the BC847 series of NPN general-purpose transistors from Nexperia. While other variants like the BC847B-QR utilize the SOT23 package, the BC847BQAZ specifically utilizes the DFN1010D-3 package. This series provides standardized performance parameters for common electronic circuit requirements across various consumer and industrial electronics.

Replacement Considerations

Direct pin-compatible substitutes may exist within the same family using different packages, such as the BC847B in SOT23. Verify that any replacement maintains the required 45V Vceo and 100mA Ic ratings. Check datasheet compatibility for hFE ranges and saturation voltages to ensure functional equivalence in the specific circuit application.
