BCV71-QR

Overview

The BCV71-QR is a PNP silicon epitaxial planar transistor manufactured by Nexperia, designed for general-purpose switching and amplification applications. It is housed in the SOT23 (TO-236AB) surface-mount package. The device features a collector-emitter voltage rating of -50 V and a continuous collector current capability of -100 mA. With a DC current gain (hFE) ranging from 160 to 320 at a collector current of -2 mA, it offers high amplification efficiency. The component operates within a junction temperature range of -55 °C to +150 °C and is qualified under the AEC-Q101 standard for automotive reliability.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards for enhanced reliability
• High DC current gain optimized for efficient signal amplification
• Robust thermal performance supporting operation up to 150 °C junction temperature

Applications

• General-purpose switching circuits in automotive electronics
• Low-power amplifier stages requiring high gain
• Interface logic level translation between different voltage domains

Procurement Notes

Verify the specific suffix QR against the official Nexperia datasheet to confirm packaging details and tape-and-reel specifications. Ensure the procurement channel provides valid traceability documentation required for automotive-grade components. Cross-reference the ordering code with the manufacturer's latest release notes to confirm availability status and any potential lifecycle changes.

Selection Notes

Select this component when a PNP transistor with moderate current handling and high gain is required in a compact SOT23 footprint. Consider the -50 V breakdown voltage and -100 mA current limits to ensure adequate headroom for the target circuit design. Verify that the thermal resistance characteristics align with the expected power dissipation constraints of the application environment.

Part Context

This part belongs to the BCV series of general-purpose transistors from Nexperia, which are widely utilized in consumer and industrial electronics. The BCV71 variant specifically targets applications needing reliable PNP switching capabilities. Its inclusion in the automotive-qualified lineup distinguishes it from standard commercial variants, ensuring suitability for harsher operating conditions.

Replacement Considerations

Consult the Nexperia replacement guide for verified equivalents. Potential substitutes may include other AEC-Q101 qualified PNP transistors in the SOT23 package with matching voltage and current ratings.
