PDTA143XQBZ

Overview

The PDTA143XQB is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an ultra-small DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. It integrates a PNP transistor with built-in bias resistors R1 and R2. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, an output current (IO) of -100 mA, and a total power dissipation (Ptot) of 340 mW at 25 °C on a standard FR4 PCB. The typical input resistance R1 is 4.7 kΩ, while the emitter-base resistor R2 is 10 kΩ. The device features a minimum DC current gain (hFE) of 50 at IC = -10 mA and VCE = -5 V.

Feature Summary

• Integrates bias resistors to simplify circuit design and reduce component count
• Ultra-thin package height of 0.5 mm suitable for space-constrained applications
• Side-wettable flanks facilitate Automatic Optical Inspection (AOI) of solder joints

Applications

• Digital switching applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix and marking code against the official Nexperia datasheet to ensure correct resistor values and package variant. Confirm that the DFN1110D-3 footprint matches the target PCB layout, paying attention to the side-wettable flank requirements for reliable soldering and inspection.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required. Ensure the -50 V rating and -100 mA current capability meet the load requirements. Consider the thermal resistance characteristics if operating in high ambient temperatures or confined spaces without adequate PCB copper area for heat dissipation.

Part Context

This part belongs to the PDTA143X/123J/143Z/114Y/124XQB series, which offers various resistor combinations within the same SOT8015 package. The NPN complement for this specific configuration is the PDTC143XQB. The series is designed as a cost-saving alternative to discrete transistor-resistor networks in digital logic and interface circuits.

Replacement Considerations

Direct pin-compatible replacements within the same series include PDTA123JQB, PDTA143ZQB, PDTA114YQB, and PDTA124XQB, provided their specific resistor ratios match the circuit requirements.
