Overview
The Nexperia PDTA143TU-QX is a PNP resistor-equipped transistor (RET) designed for surface-mount applications. It integrates a single PNP bipolar junction transistor with an internal base bias resistor, R1, specified at 4.7 kΩ. The device operates within the SOT-323 (SC-70) package and is qualified to the AEC-Q101 automotive standard. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current (Ic) of 100 mA, and a total power dissipation (Ptot) of 200 mW. The component supports a maximum junction temperature of 150°C.
Feature Summary
- Integrated bias resistor eliminates external components to simplify circuit design and reduce assembly costs.
- Automotive-grade qualification ensures reliability for demanding operational environments.
- Compact SOT-323 packaging facilitates high-density board layouts.
Applications
- General purpose switching and amplification circuits
- Inverter and interface logic circuits
- Circuit driver stages
Procurement Notes
Verify the specific suffix against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the procurement channel provides valid traceability records for AEC-Q101 qualified parts. Confirm RoHS compliance status matches current regulatory requirements before finalizing orders.
Selection Notes
Select this component when a PNP configuration with a fixed 4.7 kΩ base resistor is required. Compare the 50 V breakdown voltage and 100 mA current limits against circuit load requirements. Consider the SOT-323 footprint constraints relative to available PCB real estate and thermal management needs.
Part Context
This part belongs to the PDTA143 series of pre-biased transistors from Nexperia. The series offers various package options including SOT23 and DFN1006-3. The TU suffix specifically denotes the SOT-323 form factor, distinguishing it from other variants in the family while maintaining identical electrical characteristics.
Replacement Considerations
Direct substitutes within the same family include PDTA143TT (SOT23 package) and PDTA143TM (DFN1006-3 package). Verify pinout compatibility and physical dimensions before substituting to ensure proper fit on the existing printed circuit board.
