BC846S-QX

Overview

The BC846S-QX is an NPN general-purpose double transistor manufactured by Nexperia. It integrates two transistors within a single SOT363 (SC-88) surface-mounted device plastic package. The component is qualified according to AEC-Q101 standards, making it suitable for automotive applications. Key electrical characteristics include a maximum collector-emitter voltage of 65 V and a continuous collector current of 100 mA. The device operates reliably across a temperature range from -65 °C to +150 °C.

Feature Summary

• Two transistors integrated in one package to reduce board space
• No mutual interference between the internal transistors
• Qualified according to AEC-Q101 for automotive use

Applications

• General purpose switching
• Small signal amplification
• Automotive electronic circuits

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details such as reel size or tape width. Ensure the part number matches the exact AEC-Q101 qualified variant required for your design. Cross-reference with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when dual NPN switching or amplification functions are needed in a compact footprint. The AEC-Q101 qualification makes it appropriate for automotive environments where reliability is critical. Compare pinout compatibility with existing designs to ensure seamless integration into the PCB layout.

Part Context

This part belongs to the BC846 series of small signal bipolar transistors. The 'S' designation indicates a dual configuration in the SOT363 package. The 'Q' suffix typically denotes AEC-Q101 qualification for automotive grade reliability. This series offers a cost-effective solution for replacing discrete components with integrated dual units.

Replacement Considerations

BC846S,115 is a standard commercial grade dual NPN transistor in the same SOT363 package. BCM846BS is a matched pair variant in the same package. Verify if automotive qualification is strictly required before substituting with non-qualified equivalents.
