BC847BVNQ-7

Overview

The BC847BVNQ-7 is a complementary pair small signal transistor manufactured by Diodes Incorporated, featuring one internally isolated NPN (BC847B type) and one PNP (BC857B type) transistor within an SOT563 surface-mount package. The device is designed for automotive applications requiring specific change control and is AEC-Q101 qualified. It operates with a maximum collector current of 100mA and a total power dissipation of 150mW at 25°C. The NPN transistor offers a transition frequency of 300MHz, while the PNP transistor provides 200MHz. Maximum ratings include a collector-emitter voltage of 45V and a collector-base voltage of 50V for both polarities.

Feature Summary

• Complementary NPN/PNP configuration in a single ultra-small surface-mount package
• AEC-Q101 qualified and PPAP capable for automotive reliability standards
• Epitaxial die construction with lead-free, halogen-free, and antimony-free materials

Applications

• Automotive general-purpose switching and amplification circuits
• Low-voltage digital logic interfacing
• Signal processing in compact electronic assemblies

Procurement Notes

Verify that the ordering suffix matches the required packaging quantity and carrier type. Confirm that the component meets the specific automotive quality standards required for your design, including AEC-Q101 qualification and PPAP capability. Ensure the manufacturer's documentation is reviewed for any recent product change notifications or updates to the datasheet revision history before finalizing procurement specifications.

Selection Notes

Select this component when a complementary NPN/PNP pair is needed in a minimal footprint for automotive-grade designs. Consider the 150mW total power dissipation limit and the 833 °C/W thermal resistance when designing PCB layouts. Verify that the 45V collector-emitter breakdown voltage and 100mA continuous current ratings align with the circuit requirements. The SOT563 package dimensions must be accommodated within the available board space.

Part Context

This part belongs to the BC847 series of small signal transistors produced by Diodes Incorporated. It is specifically engineered for high-reliability environments, distinguishing itself from standard commercial variants through its automotive qualification. The SOT563 package allows for dense mounting on printed circuit boards, making it suitable for modern miniaturized electronics where space is constrained but performance and durability are critical.

Replacement Considerations

Check for other BC847BVN variants from different manufacturers such as Nexperia or NXP, ensuring they meet the same AEC-Q101 and PPAP requirements. Verify pinout compatibility and electrical parameter overlaps, particularly the hFE ranges and saturation voltages, before substituting.
