PDTD143EQAZ

Overview

The PDTD143EQAZ is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a leadless DFN1010D-3 (SOT1215) package. It features built-in bias resistors R1 and R2, both rated at 4.7 kΩ. The device supports a maximum collector-emitter voltage of 50 V and an output current capability of 500 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 60 at 50 mA and 5 V, a collector-emitter saturation voltage of 100 mV max at 50 mA, and a transition frequency of 210 MHz. Total power dissipation reaches 325 mW at 25°C ambient temperature.

Feature Summary

• Integrated bias resistors simplify circuit design and reduce component count
• AEC-Q101 qualified for automotive applications
• Ultra-thin package height of 0.37 mm suitable for space-constrained designs
• Visible and solderable side pads facilitate Automatic Optical Inspection

Applications

• Controlling IC inputs
• Switching loads
• Digital applications

Procurement Notes

Verify the specific suffix EQAZ to confirm the DFN1010D-3 package variant. Confirm AEC-Q101 qualification status if automotive compliance is required. Check RoHS3 compliance and MSL rating before integration. Ensure PCB footprint matches SOT1215 dimensions for proper thermal and mechanical performance.

Selection Notes

Select this RET when a compact NPN switching solution with integrated base drive is needed. Compare R1 and R2 values against other series members like PDTD113EQA or PDTD123EQA to match specific bias requirements. Consider the low profile and thermal resistance characteristics for high-density board layouts.

Part Context

This component belongs to the PDTD113/123/143/114EQA family of 50 V, 500 mA NPN resistor-equipped transistors. All variants share the same DFN1010D-3 package and general electrical limits but differ in internal resistor values. The PDTD143EQAZ specifically utilizes 4.7 kΩ resistors for both R1 and R2.

Replacement Considerations

Direct functional substitutes within the same family include PDTD113EQA, PDTD123EQA, and PDTD114EQA, provided the different resistor ratios are acceptable for the application. Verify pinout compatibility as all share the SOT1215 outline.
