PDTA144WU,115

Overview

The PDTA144WU,115 is a PNP resistor-equipped transistor from the Nexperia PDTA144W series, housed in an SOT323 (SC-70) surface-mount package. It integrates two internal bias resistors: R1 is typically 47 kΩ and R2 is typically 22 kΩ. The device 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 junction temperature limit is 150 °C, with an operating ambient range of -65 °C to +150 °C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Reduces pick-and-place costs through compact surface-mount packaging.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Confirm that the SOT323 package variant matches the required footprint for the target PCB layout. Ensure thermal management strategies align with the specified 200 mW power dissipation rating under expected operating conditions.

Selection Notes

Select this component when a compact PNP solution with integrated base biasing is required. The fixed 47 kΩ input resistor and 22 kΩ emitter resistor define the drive characteristics. Verify that the -50 V voltage rating and -100 mA current limits accommodate the peak loads of the application without exceeding absolute maximum ratings.

Part Context

This part belongs to the PDTA144W series of PNP resistor-equipped transistors. Other members include the PDTA144WT in SOT23 and PDTA144WM in DFN1006-3 packages. All variants share identical electrical parameters but differ in physical dimensions and thermal resistance characteristics based on their respective leadless or standard surface-mount configurations.

Replacement Considerations

Direct replacements within the same series include PDTA144WT (SOT23) and PDTA144WM (DFN1006-3). These parts offer identical electrical performance but require different footprints. Cross-package substitution requires verifying mechanical fit and soldering profile compatibility.
