Overview
The PDTA124XK,115 is a PNP Resistor-Equipped Transistor (RET) from the PDTA124X series manufactured by NXP USA Inc. It integrates bias resistors R1 and R2 with a PNP transistor in a single SOT346 (SC-59A) surface-mount package. The device features an input bias resistor R1 of 22 kΩ and an emitter-base resistance R2 of 47 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, a DC output current (IO) of -100 mA, and a total power dissipation of 250 mW at 25 °C ambient temperature. The NPN complement for this component is the PDTC124XK.
Feature Summary
- Integrates built-in bias resistors to reduce component count and simplify circuit design.
- Provides a cost-saving alternative for BC857 series applications in digital switching.
- Capable of controlling IC inputs and switching loads efficiently.
Applications
- Digital applications requiring simple switching logic.
- Controlling inputs of integrated circuits.
- Switching small loads in electronic circuits.

Selection Notes
Select the PDTA124XK variant when the SOT346 (SC-59A/TO-236) package form factor is required for the PCB layout. Ensure the design accommodates the specified 22 kΩ input bias resistor and 47 kΩ emitter-base resistor values. Confirm that the -50 V collector-emitter voltage rating meets the system's maximum voltage requirements. Consider the thermal resistance characteristics if operating near the maximum power dissipation limits.
Part Context
This component belongs to the PDTA124X family of PNP Resistor-Equipped Transistors. The family includes variants in different packages such as SOT416, SOT490, SOT883, SOT54, SOT23, and SOT323. All variants share the same internal circuit topology with R1 = 22 kΩ and R2 = 47 kΩ, differing primarily in physical package dimensions and pin configurations.
Replacement Considerations
The official NXP NPN complement is the PDTC124XK. For direct replacement in existing designs, verify compatibility with the target package type and ensure the complementary device's electrical ratings match the system requirements.
