PDTA143EQCZ

Overview

The PDTA143EQC is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an ultra-small DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. It features built-in bias resistors R1 and R2, both typically 4.7 kΩ. The device supports a maximum collector-emitter voltage of -50 V and an output current of -100 mA. Key electrical characteristics include a DC current gain (hFE) of at least 30 at -10 mA, a transition frequency of 180 MHz, and a total power dissipation of up to 450 mW on a standard PCB footprint.

Feature Summary

• Integrates bias resistors to simplify circuit design and reduce component count
• Ultra-small DFN1412D-3 package with side-wettable flanks for improved solder joint inspection
• Low profile height of 0.5 mm suitable for space-constrained designs

Applications

• Digital applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering code against the manufacturer's latest documentation to ensure correct package version and marking code. Confirm that the DFN1412D-3 footprint matches the target PCB layout requirements. Check for any recent product status changes or obsolescence notices directly from Nexperia before finalizing procurement plans.

Selection Notes

Select this component when a compact PNP switching solution with integrated biasing is required. Ensure the application voltage does not exceed the -50 V collector-emitter rating. Consider the thermal resistance values if operating near the maximum power dissipation limits. Verify compatibility with automated optical inspection processes due to the side-wettable flank package design.

Part Context

This part belongs to the PDTA143/114/124/144EQC series, which shares the same SOT8009 package but varies in internal resistor values. The PDTA143EQC specifically utilizes 4.7 kΩ resistors for both input and emitter-base paths, distinguishing it from other series members like the PDTA114EQC or PDTA144EQC.

Replacement Considerations

Direct pin-compatible replacements within the same series include PDTA114EQC, PDTA124EQC, and PDTA144EQC, provided the different internal resistor values are acceptable for the circuit design.
