BC846AW-QX

Overview

The BC846AW-QX is an NPN general-purpose bipolar junction transistor manufactured by Nexperia. It utilizes silicon technology and is housed in a SOT-323 (SC-70) surface-mount package with three terminals. The device supports a maximum collector-emitter voltage of 65 V, a collector-base voltage of 80 V, and an emitter-base voltage of 6 V. It handles a continuous collector current of 100 mA and a peak current of 200 mA. Power dissipation is rated at 200 mW. The gain-bandwidth product is 100 MHz, with a DC current gain ranging from 200 to 450 at 2 mA and 5 V. Operating temperatures span from -65 °C to +150 °C. It holds AEC-Q101 qualification.

Feature Summary

Procurement Notes

Verify the specific suffix QX against official Nexperia documentation to confirm reel packaging specifications. Ensure the part number matches the exact gain bin AW. Cross-reference the 12NC code 934663676115 for accurate ordering. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Validate that the supplier provides genuine Nexperia products to avoid counterfeit components.

Selection Notes

Select this component when automotive reliability is required alongside small form factor constraints. The SOT-323 package offers space efficiency compared to larger alternatives. The high gain range minimizes base drive requirements. Verify thermal management needs as power dissipation is limited to 200 mW. Consider the PNP complement BC857BW-Q if complementary pairs are needed in the design.

Part Context

This part belongs to the BC846xW-Q series of NPN general-purpose transistors. It shares the same package and electrical characteristics as other variants in the series, distinguished primarily by its DC current gain binning. The series is designed for automotive applications, ensuring robust performance under varying temperature conditions and strict quality standards defined by the automotive industry.

Replacement Considerations

BC846AW-QF serves as an alternative packaging option within the same family. BC847BW-Q offers similar functionality but with different voltage ratings. BC856BW-Q is the PNP complement. Direct substitution requires verifying pin compatibility and gain specifications.
