BC846SH-QX

Overview

The BC846SH-QX is a dual NPN general-purpose transistor manufactured by Nexperia. It features two closely matched transistors integrated into a single SOT363 (SC-88) surface-mount package. The device supports a maximum collector current of 100 mA and offers high breakdown voltages, including VCEO of 65 V and VCBO of 80 V. It operates within a temperature range of -65 °C to +175 °C and is qualified according to AEC-Q101 standards for automotive applications.

Feature Summary

• Dual NPN configuration with closely matched current gain to reduce component count
• Low collector-emitter saturation voltage for efficient switching
• High-temperature operation capability up to 175 °C
• Automotive qualification compliant with AEC-Q101 standards

Applications

• General-purpose switching circuits
• Amplification stages in signal processing
• Automotive electronic systems requiring high reliability

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details such as reel size or tape specifications. Ensure the order matches the exact part number variant required for your design, as suffixes often denote distinct handling or packaging attributes rather than functional changes.

Selection Notes

Select this component when space-constrained designs require two matched NPN transistors. The SOT363 package minimizes board area compared to discrete solutions. Consider its AEC-Q101 qualification if the application involves automotive environments or requires extended temperature stability beyond standard industrial ranges.

Part Context

This part belongs to the BC846 series of small-signal bipolar junction transistors. It serves as the dual-transistor counterpart to single units like the BC846W, offering integrated matching benefits. The 'Q' designation indicates automotive-grade qualification, distinguishing it from standard commercial variants while maintaining similar electrical characteristics.

Replacement Considerations

Direct replacements include other AEC-Q101 qualified dual NPN transistors in SOT363 packages. Verify pinout compatibility and thermal resistance values before substitution. Alternative parts must match the 100 mA current rating and 65 V VCEO specification to ensure circuit integrity.
