BC847S-AQ

Overview

The BC847S-AQ is a dual NPN bipolar junction transistor array manufactured by Diotec Semiconductor. It features two independent NPN transistors housed in a surface-mount SOT-363 package. The device supports a maximum collector-emitter voltage of 45V and a continuous collector current of 100mA. Key electrical characteristics include a minimum DC current gain (hFE) of 200 at 2mA and 5V, a transition frequency of 100MHz, and a maximum power dissipation of 250mW. The component operates within a temperature range of -55°C to 150°C junction temperature and complies with RoHS3 standards.

Feature Summary

• Dual NPN configuration for compact circuit integration
• Automotive-grade qualification under AEC-Q101 standards
• High current gain performance for signal amplification
• Surface-mount SOT-363 packaging for space-constrained designs

Applications

• Automotive electronic control modules
• General-purpose switching circuits
• Signal amplification stages
• Industrial sensor interfaces

Procurement Notes

Verify the specific suffix 'AQ' indicates automotive grade compliance when sourcing. Confirm package type is SOT-363 and check manufacturer datasheets for exact hFE binning requirements. Ensure supply chain partners provide traceability documentation consistent with automotive quality standards.

Selection Notes

Select this component when dual NPN functionality is required in a minimal footprint. Compare transition frequency and saturation voltage against single-transistor alternatives if higher speed or lower loss is needed. Verify thermal management capabilities align with the 250mW power dissipation limit in the target application environment.

Part Context

This part belongs to the BC847 series of small-signal transistors. The 'S' variant denotes a dual configuration, while the '-AQ' suffix typically signifies automotive qualification. It serves as a compact alternative to discrete dual-transistor setups, simplifying PCB layout for applications requiring matched or independent NPN pairs.

Replacement Considerations

BC847S is a direct parameter-equivalent substitute from the same manufacturer.
