BC847PN-AQ

Overview

The BC847PN-AQ is an automotive-grade complementary bipolar junction transistor (BJT) array manufactured by Diotec Semiconductor. It integrates one NPN and one PNP transistor within a single SOT-363 surface-mount package. The device supports a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 45 V for both polarities. Key electrical characteristics include a transition frequency (fT) of 100 MHz and a power dissipation rating of 250 mW. It operates reliably across a junction temperature range of -55°C to +150°C and complies with AEC-Q101 standards.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q101 qualification standards
• Complementary NPN/PNP configuration in a compact dual-transistor array
• High thermal stability supporting extended operating temperatures up to 150°C

Applications

• Automotive electronic control units requiring robust signal switching
• Low-power load switching applications in vehicle systems
• General-purpose amplification and switching circuits in automotive environments

Procurement Notes

Verify the specific suffix 'AQ' confirms AEC-Q101 automotive qualification status directly from the manufacturer's datasheet or official component documentation. Confirm that the SOT-363 pinout matches the target circuit design, as pin configurations can vary between manufacturers even for identical part numbers. Ensure the ordering documentation explicitly states compliance with RoHS directives before finalizing procurement.

Selection Notes

Select this component when a complementary NPN/PNP pair is required in a minimal footprint for automotive applications. The 100 mA current rating suits low-to-medium power switching tasks. Compare the 100 MHz transition frequency against system bandwidth requirements. Verify that the 250 mW power dissipation capability aligns with the thermal management strategy of the host PCB layout under expected operating conditions.

Part Context

This part belongs to the BC847 series of small-signal transistors produced by Diotec Semiconductor. While standard BC847 variants serve general commercial electronics, the '-AQ' suffix denotes an automotive-qualified version designed for higher reliability and stricter manufacturing controls. It serves as a compact alternative to discrete dual-transistor solutions, saving board space in dense automotive assemblies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers must consult official cross-reference lists from Diotec Semiconductor or verify compatibility with other AEC-Q101 qualified SOT-363 complementary BJT arrays from different manufacturers.
