PDTA143TU,115

Overview

The PDTA143TU,115 is a PNP resistor-equipped transistor manufactured by Nexperia USA Inc. It integrates a single bias resistor (R1) with a value of 4.7 kΩ, while the second resistor (R2) remains open. The device is housed in an SOT-323 surface-mount package and supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous DC output current (IO) of -100 mA. Total power dissipation is rated at 200 mW at 25 °C ambient temperature. The component operates within an ambient temperature range of -65 °C to +150 °C.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce component count
• Reduces pick and place costs during manufacturing
• Single NPN complement available for complementary designs

Applications

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

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when a compact PNP digital transistor with a 4.7 kΩ base resistor is required. Ensure the SOT-323 footprint matches the PCB layout. Verify that the -50 V voltage rating and -100 mA current capacity meet the load requirements. Consider thermal resistance limits if operating near maximum junction temperatures.

Part Context

This part belongs to the PDTA143T series of PNP resistor-equipped transistors. The series includes variants in different packages such as SOT23, SOT883, and TO-92. All members share the same electrical characteristics but differ in physical dimensions and mounting styles. The TU suffix specifically denotes the SOT-323 (SC-70) plastic surface-mounted package.

Replacement Considerations

PDTC143TU serves as the NPN complement within the same series. Other package variants like PDTA143TT (SOT23) offer identical electrical performance but require different footprints.
