PDTA143ZK,115

Overview

The PDTA143ZK,115 is a PNP resistor-equipped transistor from the PDTA143Z series manufactured by NXP Semiconductors. It integrates bias resistors R1 (4.7 kΩ) and R2 (47 kΩ) within a single SOT346 (SC-59) surface-mount package. The device supports a maximum collector-emitter voltage of -50 V and a DC output current of -100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at IC = -10 mA and VCE = -5 V, a maximum collector-base cut-off current of 100 nA, and a total power dissipation of 250 mW at an ambient temperature up to 25 °C.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce component count
• Reduces pick and place costs through integrated passive components
• Suitable for general purpose switching and amplification applications

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 package variant and manufacturing origin. Ensure compliance with RoHS directives and check for any recent product change notifications regarding lead composition or assembly location updates before finalizing procurement specifications.

Selection Notes

Select this component when space constraints require a compact SOT346 footprint. Confirm that the required base drive current aligns with the internal 4.7 kΩ resistor value. Verify thermal management requirements against the 250 mW power dissipation limit in free air conditions to ensure reliable operation under expected load profiles.

Part Context

This part belongs to the PDTA143Z series of PNP resistor-equipped transistors. The series includes various package options such as SOT23, SOT323, and SOT883. The ZK suffix specifically denotes the SOT346 (SC-59) plastic surface-mounted package configuration, distinguishing it from other physical form factors within the same electrical family.

Replacement Considerations

Direct substitutes include PDTA143ZE, PDTA143ZEF, PDTA143ZM, PDTA143ZS, PDTA143ZT, and PDTA143ZU. These alternatives share identical electrical parameters but utilize different package types such as SOT416, SC-89, DFN1006-3, TO-92, SOT23, and SOT323 respectively.
