Overview
The PDTA143XT-QR is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an SOT23 surface-mount package. It integrates a single NPN transistor with built-in bias resistors: R1 is typically 4.7 kΩ and R2 is open. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of 50 V. Total power dissipation is rated at 250 mW, with a maximum junction temperature of 150 °C. This component is AEC-Q101 qualified for automotive applications.
Feature Summary
- Integrated bias resistors simplify circuit design by reducing component count and pick-and-place costs.
- Automotive-grade qualification ensures reliability for demanding environments.
- Small SOT23 plastic package facilitates efficient surface-mount assembly.
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver applications
Procurement Notes
Verify the specific suffix 'QR' against official Nexperia documentation to confirm reel packaging specifications and tape dimensions. Ensure the part number matches the exact electrical parameters required for the target application, as suffixes may indicate variations in packaging or handling that do not alter the core semiconductor function.
Selection Notes
Select this PNP RET when a compact solution for general-purpose switching or inversion is needed. The integrated 4.7 kΩ base resistor simplifies drive requirements. Verify that the 50 V collector-emitter voltage and 100 mA current ratings exceed the maximum operational loads in the specific circuit design to ensure safe operation within thermal limits.
Part Context
This component belongs to the PDTA143T series of PNP resistor-equipped transistors. It serves as the PNP complement to the PDTC143XT NPN variant. Both devices share similar electrical characteristics and are designed to reduce board space and assembly complexity in digital logic and interface applications.
Replacement Considerations
The PDTC143XT is the complementary NPN device in the same family but differs in polarity. Direct substitution requires verifying circuit compatibility with PNP versus NPN configurations. Other SOT23-3 PNP RETs with matching 50 V/100 mA ratings may be considered if electrical parameters align.
