BCP56-16-AQ

Overview

BCP56-16-AQ is an NPN bipolar junction transistor manufactured by Diotec Semiconductor, designed for surface-mount applications in the SOT-89 (TO-243AA) package. It features a maximum collector-emitter voltage of 80 V and a continuous collector current of 1 A. The device has a power dissipation rating of 500 mW and a transition frequency of 130 MHz. It meets automotive quality standards under AEC-Q101 certification. The DC current gain (hFE) is specified as a minimum of 100 at 150 mA and 2 V. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q101 qualification standards
• High continuous collector current capability of 1 A for medium-power switching
• Low collector-emitter saturation voltage for efficient power handling
• Surface-mount SOT-89 package optimized for automated assembly

Applications

• Automotive electronic control units requiring qualified components
• Audio amplifier driver stages
• General-purpose switching circuits in industrial equipment
• Output stages in consumer electronics

Procurement Notes

Verify the specific suffix AQ indicates automotive grade compliance against the official Diotec Semiconductor datasheet. Confirm the package designation matches SOT-89 or TO-243AA physical dimensions. Ensure the manufacturer part number aligns with current production status. Cross-reference electrical parameters such as hFE and VCEO with the latest published specifications before integration.

Selection Notes

Select this component when automotive qualification is mandatory for NPN switching applications. The 1 A current rating suits moderate power loads where SOT-89 thermal performance is sufficient. Compare hFE ranges and saturation voltages against alternative BJT families if higher gain or lower loss is required. Verify compatibility with PCB footprint constraints associated with the three-terminal surface-mount outline.

Part Context

The BCP56 series represents NPN medium-power transistors commonly used in audio and general-purpose amplification. The -16 variant typically denotes a specific DC current gain binning group within the family. The -AQ suffix distinguishes the automotive-qualified version from standard commercial grades, ensuring stricter manufacturing controls and long-term stability for vehicle environments.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include BCX56-16, BCX56-16-TP, BCX56-16HE3-TP, and BCX56-16TF. Verify that replacement parts match the SOT-89 package and AEC-Q101 requirements if automotive use is intended.
