PDTA114YQCZ

Overview

The PDTA114YQC 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 is typically 10 kΩ and R2 is typically 47 kΩ, yielding a ratio of approximately 4.7. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous output current (IO) of -100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at VCE = -5 V and IC = -10 mA, and a typical transition frequency (fT) of 180 MHz. The package dimensions are 1.4 x 1.2 x 0.48 mm.

Feature Summary

• Integrates a PNP transistor with two built-in bias resistors to simplify circuit design and reduce component count.
• Utilizes a compact DFN1412D-3 leadless package with side-wettable flanks for improved solder joint visibility during Automatic Optical Inspection (AOI).
• Offers high breakdown voltage and 100 mA output current capability suitable for digital switching applications.

Applications

• Digital logic applications and interface circuits
• Controlling inputs for integrated circuits
• Switching loads in portable equipment

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 DFN1412D-3 footprint matches the target PCB layout, paying attention to the side-wettable flank requirements for reflow soldering processes.

Selection Notes

Select this component when space constraints require a leadless package with visible solder joints for quality inspection. Ensure the required base drive current aligns with the 10 kΩ input resistor value. Verify that the -50 V collector-emitter voltage rating exceeds the maximum operating voltage in the application circuit.

Part Context

This part belongs to the PDTA143X/123J/143Z/114Y/124XQC series, which shares the same SOT8009 package but varies in internal resistor values. It serves as a surface-mount alternative to through-hole discrete transistor-resistor combinations, offering reduced pick-and-place costs and simplified assembly workflows for high-volume manufacturing.

Replacement Considerations

Direct replacements within the same series include PDTA143XQC, PDTA123JQC, PDTA143ZQC, and PDTA124XQC, provided the different resistor ratios are acceptable for the circuit design. Cross-package equivalents like the PDTA114YT (SOT23) may be considered if footprint changes are permissible.
