PDTA144TK,115

Overview

The PDTA144TK,115 is a PNP resistor-equipped transistor from the PDTA144T series manufactured by Nexperia. It integrates a single bias resistor (R1) with a nominal value of 47 kΩ, while the second resistor (R2) remains open. The device operates in a SOT346 surface-mount package and provides a collector-emitter voltage (VCEO) rating of -50 V and a continuous DC output current (IO) of -100 mA. Key electrical characteristics include a maximum total power dissipation of 250 mW at 25 °C ambient temperature and a minimum DC current gain (hFE) of 100 at an IC of -1 mA.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Reduces pick and place costs through integrated discrete functionality.
• Designed for general-purpose switching, amplification, and interface applications.

Applications

• General purpose switching and amplification
• Inverter and interface circuits
• Circuit driver

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact tape-and-reel quantity and manufacturing origin. Confirm that the SOT346 package variant aligns with your PCB footprint requirements. Ensure compliance with RoHS directives and check for any automotive qualification status if required for your specific deployment environment.

Selection Notes

Select this component when a compact PNP solution with a fixed 47 kΩ base input resistor is required. The SOT346 package offers a small form factor suitable for space-constrained designs. Verify that the -50 V collector-emitter voltage and -100 mA current limits meet the operational demands of the target circuit application.

Part Context

This part belongs to the PDTA144T series of PNP resistor-equipped transistors. The series includes various package options such as SOT23, SOT323, and TO-92. The PDTA144TK specifically utilizes the SOT346 package, which is equivalent to the SC-59 standard. The NXP Standard Product business was rebranded as Nexperia in 2017.

Replacement Considerations

Direct functional equivalents within the same series include PDTA144TT (SOT23), PDTA144TU (SOT323), and PDTA144TS (TO-92). These parts share identical electrical specifications but differ in physical package dimensions and pinout orientation. Verify mechanical compatibility before substitution.
