PDTC143TU/ZLX

Overview

The PDTC143TU/ZLX is an NPN resistor-equipped transistor (RET) from the PDTC143T series, manufactured by Nexperia. It integrates a single bias resistor (R1 = 4.7 kΩ) with an open R2 configuration within a SOT323 (SC-70) surface-mount package. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous DC output current (IO) of -100 mA. Key electrical characteristics include a maximum collector-base cut-off current of 100 nA at VCB = 50 V and a minimum DC current gain (hFE) of 200 at IC = 1 mA. Thermal resistance from junction to ambient in free air is specified at 625 K/W for the SOT323 package.

Feature Summary

Built-in bias resistors simplify circuit design and reduce component count.
Reduces pick and place costs through integrated passive components.

Applications

General purpose switching
Amplification circuits
Inverter and interface circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm manufacturing origin and compliance details. Confirm that the SOT323 package dimensions align with the target PCB footprint requirements. Ensure the supply chain source provides valid traceability records for the discrete semiconductor batch.

Selection Notes

Select this component when a compact NPN switching solution with integrated base biasing is required. The SOT323 package offers space efficiency compared to larger leaded alternatives. Verify that the 4.7 kΩ internal resistor value meets the specific drive requirements of the application logic levels.

Part Context

This part belongs to the PDTC143T 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.

Replacement Considerations

The PDTA143TU serves as the PNP complement within the same series. Other package variants like PDTC143TT or PDTC143TK may be considered if different form factors are needed, provided pinout compatibility is verified.
