Overview
The PDTA143XU-QX is a PNP pre-biased transistor manufactured by Nexperia USA Inc. It integrates a single PNP bipolar junction transistor with internal biasing resistors in an SC-70 (SOT-323) surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a maximum DC collector current of 100 mA. Internal resistance values include R1 at 4.7 kOhms and R2 at 47 kOhms. Key electrical parameters specify a minimum DC current gain (hFE) of 100 at 10 mA and 5 V, with a maximum collector-emitter saturation voltage of 200 mV at 250 µA base current and 5 mA collector current. Power dissipation is rated at 200 mW.
Feature Summary
- Integrates PNP transistor with built-in biasing resistors to reduce component count
- Designed for high-density surface-mount applications using compact SC-70 packaging
- Provides simplified circuit design through integrated resistor network
Applications
- Switching applications in portable consumer electronics
- Driver circuits for low-power loads in mobile devices
- Logic level translation and interface buffering in embedded systems
Procurement Notes
Verify the specific suffix 'QX' against official Nexperia documentation to confirm tape-and-reel packaging specifications and compliance status. Ensure the ordering part number matches the required AEC-Q101 qualification if automotive grade performance is necessary for the target application environment.
Selection Notes
Select this component when a compact PNP switching solution with integrated biasing is required. Compare the 50 V rating and 100 mA current limit against load requirements. Verify that the SC-70 footprint fits the PCB layout constraints and that the internal resistor values align with the driving logic levels.
Part Context
This part belongs to the Nexperia PDTA143 series of pre-biased transistors. It shares functional similarities with variants like PDTA143ZU but differs in packaging or specific qualification grades. The series is designed to simplify digital switching circuits by replacing discrete transistor-resistor networks with a single surface-mount component.
Replacement Considerations
Direct substitutes include PDTA143ZU and PDTA143TT within the same family. Verify pinout compatibility and electrical parameter equivalence before substitution. Confirm that alternative packages meet the thermal and spatial requirements of the existing design.
