PDTA124EK,115

Overview

The PDTA124EK,115 is a PNP resistor-equipped transistor from the PDTA124E series manufactured by NXP USA Inc. It integrates two bias resistors (R1 and R2) with a single PNP transistor in a compact SOT346 (SC-59) surface-mount package. The device features a collector-emitter voltage of -50 V and a DC output current of -100 mA. Each internal bias resistor has a typical value of 22 kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 60 at -5 mA, a saturation voltage of -150 mV at -10 mA, and an input-off voltage of -1.1 V.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count
• Reduces pick-and-place costs through consolidated packaging
• Provides standardized switching and amplification capabilities

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest product status documentation. Confirm that the SOT346 package variant matches the required footprint for the target PCB layout. Ensure compliance with RoHS directives if applicable to the manufacturing region. Cross-reference the datasheet revision date to confirm the accuracy of thermal resistance values before finalizing the bill of materials.

Selection Notes

Select this component when space constraints require combining a PNP transistor with base and emitter biasing resistors. The SOT346 package offers a small form factor suitable for dense surface-mount assemblies. Verify that the -50 V collector-emitter rating meets the maximum voltage requirements of the application circuit. Consider the integrated 22 kΩ resistor values to ensure proper biasing without external components.

Part Context

This part belongs to the PDTA124E series of PNP resistor-equipped transistors. The series includes multiple package options such as SOT23, SOT323, and SOT883. The PDTA124EK specifically utilizes the SOT346 (SC-59) plastic surface-mounted package. The NPN complement for this device is the PDTC124EK.

Replacement Considerations

Direct substitutes within the same series include PDTA124ET (SOT23), PDTA124EU (SOT323), and PDTA124EM (SOT883). These alternatives share identical electrical specifications but differ in physical package dimensions. Verify pinout compatibility and thermal dissipation requirements when substituting packages.
