BCX52-16-QX

Overview

The BCX52-16-QX is a PNP medium power transistor manufactured by Nexperia, designed for surface-mount applications. It operates with a maximum collector-emitter voltage (VCEO) of -60 V and a maximum collector-base voltage (VCBO) of 60 V. The device supports a continuous DC collector current (Idc) of -1 A and features a minimum DC current gain (hFE) of 63. Power dissipation capabilities vary by package: the UPAK variant handles up to 1.3 W, while the SOT-89 variant is rated at 500 mW. The component includes an exposed heatsink for thermal management and meets AEC-Q101 automotive qualification standards.

Feature Summary

• AEC-Q101 qualified for high-performance automotive applications
• Exposed heatsink design for excellent thermal and electrical conductivity
• High current capability with three available current gain selections

Applications

• Linear voltage regulators
• High-side switches
• Battery-driven devices
• Power management MOSFET drivers
• Amplifiers

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and ensure the selected variant matches the required thermal dissipation profile for the target application environment.

Selection Notes

Select this component for designs requiring robust PNP switching or amplification in space-constrained environments. The exposed pad facilitates efficient heat transfer, making it suitable for moderate power applications where standard packages may overheat. Ensure the circuit design accounts for the specified hFE range and thermal resistance characteristics.

Part Context

This part belongs to the BCX52 series of PNP medium power transistors. It shares core electrical specifications with variants like BCX52-16 but differs in packaging options such as UPAK and SOT-89. The series is engineered for general-purpose use in consumer and automotive electronics, balancing performance with compact form factors.

Replacement Considerations

Check for direct substitutes within the BCX52 family or equivalent PNP transistors with matching VCEO, Idc, and package dimensions. Verify that any replacement maintains AEC-Q101 qualification if used in automotive contexts.
