Overview
The PDTA143XMB,315 is a PNP Resistor-Equipped Transistor (RET) housed in a leadless ultra-small SOT883B (DFN1006B-3) plastic package. It integrates an NPN transistor with built-in bias resistors to simplify circuit design and reduce component count. The device features a collector-emitter voltage (VCEO) of -50 V and a continuous output current (IO) of -100 mA. The internal input bias resistor (R1) has a typical value of 4.7 kΩ, while the R2/R1 ratio typically measures 2.1. Total power dissipation reaches 250 mW at 25 °C ambient temperature, with a maximum junction temperature of 150 °C.
Feature Summary

- Leadless ultra-small SMD plastic package with low profile height
- Qualified for automotive applications under AEC-Q101 standards
Applications
- Low-current peripheral driver
- Control of IC inputs
- Replaces general-purpose transistors in digital applications
- Mobile applications
Procurement Notes
Verify the specific ordering suffix
Selection Notes
Select this PNP RET when space constraints require a compact DFN1006B-3 footprint. Ensure the -50 V collector-emitter rating meets the circuit's voltage requirements. Verify that the integrated 4.7 kΩ input resistor aligns with the desired base drive characteristics compared to discrete transistor solutions.
Part Context
This component belongs to the PDTA143 series of resistor-equipped transistors manufactured by Nexperia. It serves as the PNP counterpart to the PDTC143XMB NPN variant. Both devices utilize the same SOT883B package and share similar electrical profiles, differing primarily in polarity and internal resistor configurations.
Replacement Considerations
The PDTC143XMB is the direct NPN complement within the same package family. For pin-compatible replacements, verify the polarity requirement; if a PNP solution is needed, check other PDTA series members like PDTA143TM or PDTA143TT, ensuring the package type matches the PCB layout.
FAQ
What are the values of the built-in bias resistors?
The input bias resistor (R1) has a typical value of 4.7 kΩ. The second resistor (R2) creates a typical R2/R1 ratio of 2.1.
Is this component suitable for automotive use?
Yes, the PDTA143XMB is qualified in accordance with the Automotive Electronics Council (AEC) standard Q101.
What is the maximum total power dissipation?
The total power dissipation (Ptot) is rated at 250 mW when the ambient temperature is 25 °C or lower.
