BCP51-16TF

Overview

The Nexperia BCP51-16TF is a PNP medium power transistor housed in an SOT223 (SC-73) surface-mounted package. It features a collector-emitter voltage of -45 V and a continuous collector current of -1 A, with peak pulse capability up to -2 A. The device offers three current gain selections; the -16 variant specifies a DC current gain range of 100 to 250 at -150 mA. It includes an exposed heatsink for thermal management and is qualified under AEC-Q101 standards.

Feature Summary

• High collector current capability supporting both continuous and pulsed operation
• Three distinct current gain selections available within the series
• Exposed heatsink design providing enhanced thermal and electrical conductivity
• Qualified for automotive applications according to AEC-Q101 standards

Applications

• Linear voltage regulators
• MOSFET drivers
• High-side switches

Procurement Notes

Verify the specific ordering suffix matches the required gain bin. Confirm the package type corresponds to SOT223. Ensure the component meets AEC-Q101 requirements if used in automotive designs. Check the latest datasheet revision for any updates to absolute maximum ratings or thermal characteristics before finalizing the bill of materials.

Selection Notes

Select this component when a PNP transistor requires high current handling in a compact surface-mount form factor. The -16 suffix indicates a specific gain range suitable for precise biasing applications. Consider the exposed pad thermal performance based on the PCB copper area. Verify that the operating voltage remains within the -45 V limit during transient conditions.

Part Context

This part belongs to the BCX51T/BCP51T family of medium power transistors from Nexperia. The series provides complementary NPN options and different gain grades. The BCP51-16TF specifically targets designs needing reliable switching or amplification in space-constrained environments while maintaining automotive-grade reliability standards.

Replacement Considerations

Direct substitutes include other BCP51-16 variants from Nexperia. Cross-reference pinouts and thermal resistance values when considering alternative manufacturers. Ensure the replacement maintains the same SOT223 footprint and AEC-Q101 qualification status.
