PDTC144WT,215

Overview

The PDTC144WT,215 is an NPN resistor-equipped transistor (RET) manufactured by Nexperia. It integrates a single NPN bipolar junction transistor with two internal bias resistors: R1 (base resistor) of 47 kΩ and R2 (emitter-to-base resistor) of 22 kΩ. The device is housed in the SOT-23 surface-mount package. Key electrical ratings include a collector-emitter voltage (VCEO) of -50 V, a continuous DC output current (IO) of -100 mA, and a peak collector current (ICM) of -100 mA. Thermal characteristics specify a total power dissipation (Ptot) of 250 mW at an ambient temperature up to 25 °C, with a maximum junction temperature (Tj) of 150 °C.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce component count.
• Reduces pick and place costs during manufacturing.
• Single NPN configuration with integrated base and emitter-base resistors.

Applications

• General purpose switching and amplification

Selection Notes

Select this part for applications requiring a compact NPN switching solution with integrated biasing. The SOT-23 package suits space-constrained designs. Ensure the required input resistance matches the 47 kΩ specification and that the 50 V voltage rating accommodates the circuit's maximum operating conditions.

Part Context

This component belongs to the PDTC144W series of NPN resistor-equipped transistors. The series includes variants with different packages such as SOT883, SOT323, and TO-92. The PDTA144WT is the PNP complement within the same family. All series members share identical electrical characteristics but differ in physical footprint and pinning configurations.

Replacement Considerations

The PDTA144WT serves as the direct PNP complement within the same product family. Other PDTC144W series members like PDTC144WM or PDTC144WU offer equivalent electrical performance in alternative packages such as DFN1006-3 or SC-70.
