Overview
The PDTC124XK,115 is an NPN Resistor-Equipped Transistor (RET) from the PDTC124X series manufactured by Nexperia. It integrates a single NPN transistor with built-in bias resistors R1 and R2 within a SOT346 (SC-59A/TO-236) surface-mount package. The device features a collector-emitter voltage (VCEO) of 50 V and a continuous output current (IO) of 100 mA. The typical input bias resistor R1 is 22 kΩ, with a resistance range of 15.4 kΩ to 28.6 kΩ. The internal resistor ratio R2/R1 has a typical value of 2.1. The component operates within an ambient temperature range of -65 °C to +150 °C.
Feature Summary
- Integrates NPN transistor with built-in bias resistors to reduce component count
- Simplifies circuit design for general-purpose switching and amplification
- Reduces pick and place costs in automated assembly processes
Applications
- General-purpose switching and amplification circuits
- Circuit drivers
- Inverter and interface circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and regional manufacturing origin. Confirm that the SOT346 package variant aligns with the required PCB footprint and thermal dissipation constraints for the target application environment.
Selection Notes
Select this component when a compact NPN solution with integrated base biasing is required. Ensure the 50 V collector-emitter voltage rating exceeds the maximum operating voltage. Verify that the 22 kΩ input resistor value provides appropriate base drive current for the intended load conditions without exceeding the 100 mA output current limit.
Part Context
This part belongs to the PDTC124X family of NPN resistor-equipped transistors. Other variants in the series include PDTC124XE (SOT416), PDTC124XEF (SOT490), PDTC124XM (SOT883), PDTC124XS (SOT54), PDTC124XT (SOT23), and PDTC124XU (SOT323). All share identical electrical characteristics but differ in physical package dimensions and pin configurations.
Replacement Considerations
Direct functional replacements within the same series include PDTC124XE, PDTC124XEF, PDTC124XM, PDTC124XS, PDTC124XT, and PDTC124XU. Substitution requires verifying package compatibility and pinout alignment, as the SOT346 pin configuration differs from other packages in the family.
