BC806-25H-QR

Overview

The Nexperia BC806-25H-Q is an automotive-grade PNP general-purpose transistor housed in a compact SOT23 (TO-236AB) surface-mounted device plastic package. It supports a collector-emitter voltage of -80 V and a continuous collector current of -500 mA, with peak pulse capabilities reaching -1 A. The component features two distinct DC current gain selections; the BC806-25H-Q variant provides a minimum hFE of 160 at IC = -100 mA and VCE = -1 V. Qualified under AEC-Q101 standards, it operates reliably in high-temperature environments up to a junction temperature of 175 °C.

Feature Summary

• Qualified for automotive applications according to AEC-Q101 standards
• Supports high-temperature operation with a maximum junction temperature of 175 °C
• Offers two selectable DC current gain ranges for flexible design integration

Applications

• General-purpose switching circuits
• Signal amplification stages
• 48 V automotive board net interfaces

Procurement Notes

Verify the specific ordering suffix matches the required current gain bin, as the BC806-25H-Q designation corresponds to a defined hFE range. Confirm that the SOT23 package orientation aligns with the target PCB footprint. Ensure the application environment remains within the specified thermal limits to maintain reliability. Cross-reference the marking code QP% for production identification during assembly inspection.

Selection Notes

Select this component when a robust PNP transistor is required for automotive systems operating on 48 V architectures. The BC806-25H-Q offers higher current gain than the BC806-16H-Q variant, making it suitable for low-drive applications. Consider the SOT23 package constraints for space-limited designs. Evaluate thermal dissipation requirements against the provided derating curves to ensure safe operation under continuous load conditions.

Part Context

This part belongs to the Nexperia BC806H-Q series, which includes complementary NPN devices such as the BC816-25H-Q. The series is engineered specifically for automotive durability, sharing common packaging and qualification standards across its variants. It serves as a specialized alternative to standard industrial transistors where extended temperature ranges and automotive reliability are mandatory.

Replacement Considerations

The BC806-25H-Q can be functionally replaced by other AEC-Q101 qualified PNP transistors in the SOT23 package with matching voltage and current ratings. Verify that substitute parts meet the same hFE minimum of 160 and support the 175 °C junction temperature requirement to maintain system integrity.
