PDTA143ZQAZ

Overview

The PDTA143ZQAZ is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in a leadless DFN1010D-3 (SOT1215) package with visible side pads. It features built-in bias resistors R1 of 4.7 kΩ and R2 of 47 kΩ. The device supports a collector-emitter voltage (VCEO) of -50 V and an output current (IO) of -100 mA. Key electrical characteristics include a DC current gain (hFE) of at least 100 at IC = -10 mA and VCE = -5 V, and a collector-emitter saturation voltage (VCEsat) of -100 mV max at IC = -5 mA. The transition frequency (fT) is typically 180 MHz.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Qualified for automotive applications under the AEC-Q101 standard.
• Features a low profile height of 0.37 mm suitable for space-constrained designs.
• Includes solderable side pads compatible with Automatic Optical Inspection (AOI).

Applications

• Digital switching applications in automotive and industrial segments.
• Controlling inputs for integrated circuits.
• Switching loads as a cost-effective alternative to BC847/BC857 series.

Procurement Notes

Verify the specific ordering suffix 'QAZ' against official Nexperia documentation to confirm packaging details such as reel specifications or tape-and-reel dimensions. Ensure that the procurement channel provides traceability to the original manufacturer's quality standards. Cross-reference the binary marking code '11 01 01' on received components to validate authenticity and correct part identification before integration into production lines.

Selection Notes

Select this component when a PNP transistor with a 4.7 kΩ base resistor and 47 kΩ emitter-base resistor is required. The DFN1010D-3 package is appropriate for high-density surface-mount layouts. Consider the -50 V breakdown voltage and -100 mA current limits during circuit design. Verify thermal dissipation requirements against the specified junction-to-ambient resistance values for the target PCB footprint.

Part Context

This device belongs to the PDTA143X/123J/143Z/114YQA series of 50 V, 100 mA PNP resistor-equipped transistors. It serves as the PNP counterpart to the PDTC143ZQA NPN RET. The series shares the same SOT1215 package and general form factor, differing primarily in internal resistor ratios and complementary polarity configurations within the Nexperia discrete semiconductor portfolio.

Replacement Considerations

The PDTC143ZQA is the documented NPN complement within the same family. For direct pin-compatible replacements, verify equivalent resistor values and voltage ratings in competitor datasheets. No other specific substitute part numbers are confirmed in the provided source material.
