PDTA124EQAZ

Overview

The PDTA124EQAZ is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in a leadless DFN1010D-3 (SOT1215) package with visible solderable side pads. It features built-in bias resistors R1 and R2, both nominally 22 kΩ. The device supports a collector-emitter voltage of -50 V and an output current of -100 mA. It is AEC-Q101 qualified for automotive use and operates within an ambient temperature range of -55 °C to +150 °C.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count
• Ultra-thin leadless package with visible side pads for Automatic Optical Inspection
• Qualified for automotive applications under AEC-Q101 standards

Applications

• Digital logic applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the complete part number against official Nexperia documentation to ensure correct suffix alignment. Confirm that the specific ordering code matches the required package variant and marking scheme. Cross-reference the binary marking code on received components to validate authenticity and traceability before integration into production lines.

Selection Notes

Select this component when space-constrained PCB layouts require a compact solution for digital switching or input buffering. The integrated resistor network eliminates external biasing components, reducing assembly complexity. Ensure the 22 kΩ internal resistance values align with the target drive currents and voltage levels of the controlled interface circuits.

Part Context

This device belongs to the PDTA143/114/124/144EQA series of 50 V, 100 mA PNP RETs. It serves as a cost-saving alternative to discrete transistor and resistor combinations, specifically replacing BC847/BC857 series equivalents in digital applications while offering improved footprint efficiency through its DFN1010D-3 packaging.

Replacement Considerations

PDTC124EQA is the NPN complement within the same series.
