Overview
The PDTA144EM,315 is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in the SOT883 (SC-101) leadless ultra-small plastic package. It integrates two bias resistors with nominal values of R1 = 47 kΩ and R2 = 47 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, an output current (IO) of -100 mA, and a total power dissipation (Ptot) of -250 mW at 25 °C. The device features a thermal resistance (Rth(j-a)) of 500 K/W and meets AEC-Q101 qualification standards for automotive applications.
Feature Summary
- Integrates built-in bias resistors to reduce component count and simplify circuit design.
- Qualified under AEC-Q101 standards for use in automotive digital applications.
- Designed as a cost-saving alternative to discrete transistor series in digital switching tasks.
Applications

Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details. Ensure compatibility with reflow soldering processes as specified in the datasheet. Confirm that the SOT883 package dimensions align with the target PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when a compact PNP solution with integrated biasing is required for space-constrained designs. The SOT883 package offers a small form factor suitable for high-density boards. Consider the -50 V voltage rating and -100 mA current capability to ensure adequate headroom for the intended load switching or input control application.
Part Context
This part belongs to the PDTA144E series of PNP resistor-equipped transistors. Other variants in the series include PDTA144EE (SOT416), PDTA144ET (SOT23), and PDTA144EU (SOT323). All share similar electrical characteristics but differ in package type and physical dimensions, allowing designers to choose based on board space and mounting preferences.
Replacement Considerations
PDTC144EM is the NPN complement within the same family. For direct replacement, verify pinout compatibility and ensure the substitute part matches the required PNP configuration and resistor values specified in the original design.
