Overview
The PDTB143EQAZ is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in a leadless DFN1010D-3 (SOT1215) package. It features built-in bias resistors R1 and R2, both valued at 4.7 kΩ with ±10% tolerance. The device supports a collector-emitter voltage of -50 V and an output current of -500 mA. Key electrical characteristics include a DC current gain (hFE) of 60 at -50 mA and -5 V, a saturation voltage of -100 mV at -50 mA, and a transition frequency of 150 MHz. Total power dissipation reaches 325 mW at 25°C.
Feature Summary
- Integrates dual bias resistors to simplify circuit design and reduce component count
- Qualified for automotive applications under AEC-Q101 standards
- Ultra-thin package profile suitable for automatic optical inspection
Applications
- Digital logic applications
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and marking codes. Confirm that the DFN1010D-3 footprint matches the PCB layout requirements. Check for RoHS3 compliance status and moisture sensitivity level before finalizing procurement orders.
Selection Notes
Select this component when a compact PNP switching solution with integrated base biasing is required. Ensure the 4.7 kΩ resistor values align with the target drive currents. Verify that the -500 mA current rating meets the load requirements and that the thermal resistance characteristics are sufficient for the intended operating environment.
Part Context
This part belongs to the PDTB113/123/143/114EQA series, which shares identical physical dimensions and general performance profiles. Variations within the series are defined by different internal resistor values, such as 1 kΩ or 10 kΩ, while maintaining the same 50 V and 500 mA ratings.
Replacement Considerations
Direct substitutes within the same family include PDTB113EQAZ, PDTB123EQAZ, and PDTB114EQAZ. These parts share the same package and electrical limits but differ in internal resistor values.
