BC846S-QF

Overview

The BC846S-QF is an NPN general-purpose double transistor manufactured by Nexperia. It features two fully isolated transistors within a single SOT363-3 (SC-88) surface-mount package. The device is qualified according to AEC-Q101 standards, making it suitable for automotive applications. Key electrical parameters include a collector-emitter voltage of 65 V and a maximum DC collector current of 100 mA per transistor. The unit operates within a temperature range of -65 °C to +150 °C junction temperature.

Feature Summary

• Two NPN transistors integrated in one compact package to reduce component count and board space
• Fully isolated internal structure preventing mutual interference between the two transistors
• Qualified according to AEC-Q101 standards for automotive reliability

Applications

• General purpose switching circuits
• Small signal amplification stages
• Automotive electronic systems requiring AEC-Q101 qualified components

Procurement Notes

Verify the specific suffix 'QF' against official Nexperia documentation to confirm tape and reel specifications. Confirm AEC-Q101 qualification status directly with the manufacturer or authorized distributors. Ensure the sourcing channel provides valid traceability for automotive-grade components.

Selection Notes

Select this component when dual NPN switching or amplification is required in a minimal footprint. The AEC-Q101 qualification makes it appropriate for automotive designs. Compare thermal resistance and gain matching requirements against alternative dual transistor packages if board space allows.

Part Context

This part belongs to the BC846 series of small-signal NPN transistors. The 'S' indicates the dual configuration in an SOT363 package, while the '-Q' suffix denotes automotive qualification. It serves as a compact solution for replacing discrete dual transistor arrangements in modern electronics.

Replacement Considerations

Check for direct equivalents such as BC846S variants from other manufacturers that meet AEC-Q101 standards. Verify pinout compatibility with the SOT363 package before substitution.
