Overview
The BC846BW-QX is an NPN general-purpose bipolar junction transistor manufactured by Nexperia. It utilizes silicon technology and is housed in a compact SOT-323 (SC-70) surface-mount package. The device supports a maximum continuous collector current of 100 mA and a peak collector current of 200 mA. Key electrical ratings include a collector-emitter voltage (VCEO) of 65 V, a collector-base voltage (VCBO) of 80 V, and an emitter-base voltage (VEBO) of 6 V. It features a DC current gain (hFE) ranging from 200 to 450 at 2 mA and 5 V, with a transition frequency (fT) of 100 MHz. Power dissipation is rated at 200 mW, and it operates within a temperature range of -65°C to +150°C.

Procurement Notes
Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details and reel specifications. Ensure the component meets AEC-Q101 requirements if used in automotive designs. Cross-reference the part number alias 934663690115 for internal tracking. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before final procurement.
Selection Notes
Select this component when a small form factor is required alongside high current gain characteristics. The SOT-323 package offers space efficiency compared to larger alternatives like SOT-23. The B-grade gain binning provides tighter performance consistency for amplification tasks. Consider the 200 mW power dissipation limit when designing thermal management solutions for dense PCB layouts.
Part Context
This part belongs to the BC846 family of NPN transistors, which includes variants such as BC846A and BC846B offering different gain ranges. The 'W' suffix indicates the SOT-323 package, while 'Q' denotes automotive qualification. The BC846BW-QX specifically combines the higher gain B-bin with the qualified automotive version in the SC-70 footprint, distinguishing it from standard commercial grades or other package types.
Replacement Considerations
Official substitutes within the same family include BC846AW-QX and BC846B-QX, provided the package and gain specifications align with design requirements.
