PDTC143ZK,115

Overview

The PDTC143ZK,115 is an NPN resistor-equipped transistor from the PDTC143Z series manufactured by Nexperia. It integrates a base bias resistor (R1) of 4.7 kΩ and an emitter-base resistor (R2) of 47 kΩ within a single SOT346 (SC-59) surface-mount package. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous DC output current (IO) of -100 mA. Total power dissipation is rated at 250 mW under standard mounting conditions. The component operates across an ambient temperature range of -65 °C to +150 °C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design
• Reduces overall component count in switching applications
• Facilitates automated assembly through reduced pick-and-place costs

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm the exact physical package dimensions and marking code. Confirm that the SOT346 footprint matches the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. Ensure the thermal resistance characteristics of the SOT346 package align with the expected power dissipation levels in the target application environment.

Part Context

This part belongs to the PDTC143Z series of NPN resistor-equipped transistors. The series includes various package options such as SOT23, SOT323, and SOT883, all sharing identical electrical characteristics but differing in physical form factors. The PDTC143ZK specifically utilizes the SOT346 outline.

Replacement Considerations

The PDTA143ZK serves as the PNP complement within the same series. Other PDTC143Z variants may be considered if package flexibility exists, provided the pinout configuration remains compatible with the existing board layout.
