BCX53-10-QX

Overview

The BCX53-10-QX is a PNP power bipolar transistor manufactured by Nexperia, designed for surface-mount applications. It operates within the BCX53 series and utilizes a UPAK (SOT89) plastic package with four terminals. The device supports a maximum collector current of -1 A and withstands a collector-emitter voltage of -60 V. Key electrical specifications include a collector-base voltage of 80 V, an emitter-base voltage of 5 V, and a minimum DC current gain (hFE) of 40. Thermal performance allows for a maximum power dissipation of 1.3 W, with an operating temperature range from -55°C to +150°C. The component meets AEC-Q101 automotive qualification standards.

Procurement Notes

Verify the specific suffix '-QX' against official Nexperia documentation to confirm exact binning or tape-and-reel specifications. Ensure the selected variant matches the required current gain group and thermal characteristics for your design. Cross-reference the datasheet revision date to guarantee compatibility with your manufacturing processes and quality requirements.

Selection Notes

Select this component when designing circuits requiring a robust PNP transistor with automotive qualification. The -10 suffix typically indicates a specific hFE bin; verify if this gain range suits your amplifier or switch design. Consider the UPAK package's thermal resistance and pinout compatibility during layout. Compare against complementary NPN types in the same family if push-pull configurations are needed.

Part Context

This part belongs to the BCX53 series of power bipolar transistors from Nexperia. The series includes various voltage ratings and polarity options, such as the BCX52 and BCX54 variants. These devices are engineered for general-purpose power switching and amplification tasks. The BCX53 specifically offers a balance of current handling and voltage blocking suitable for mid-power electronic systems.

Replacement Considerations

Direct substitutes may include other AEC-Q101 qualified PNP transistors in SOT89 packages with similar -60V VCEO and -1A IC ratings. Verify pinout compatibility and thermal performance before substitution. Consult Nexperia's official replacement guide for validated cross-references.
