PDTC124TU,115

Overview

The PDTC124TU,115 is an NPN resistor-equipped transistor from the PDTC124T series manufactured by Nexperia. It integrates a single bias resistor (R1) of 22 kΩ with the emitter-base junction left open (R2). The device is housed in a SOT323 surface-mount package and supports a collector-emitter voltage (VCEO) of -50 V and a continuous DC output current (IO) of -100 mA. Thermal characteristics include a total power dissipation of 200 mW at 25 °C ambient temperature and a thermal resistance from junction to ambient of 625 K/W. 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 for automated assembly processes.

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 dimensions align with the target PCB footprint requirements. Ensure that the absolute maximum ratings are not exceeded during operation to prevent permanent damage to the semiconductor junction.

Selection Notes

Select this component when a compact NPN solution with integrated base biasing is required. The SOT323 package offers a small form factor suitable for space-constrained designs. Verify that the 22 kΩ internal resistor value meets the specific drive requirements of the application logic levels.

Part Context

This part belongs to the PDTC124T series of NPN resistor-equipped transistors. The series includes various package options such as SOT23, SOT416, and SOT883. The TU suffix specifically denotes the SOT323 (SC-70) plastic surface-mounted package variant containing three leads.

Replacement Considerations

Compatible PNP complements within the same series include the PDTA124TU. Other package variants like the PDTC124TT or PDTC124TE may serve as functional alternatives if the physical footprint allows for different pin configurations.
