Overview
The PDTA143EU/ZLX is a PNP Resistor-Equipped Transistor (RET) from the PDTA143E series, manufactured by Nexperia USA Inc. It integrates a single PNP transistor with built-in bias resistors R1 and R2 into a SOT323 (SC-70) surface-mount package. The device supports a maximum collector-emitter voltage of -50 V and an output current of -100 mA. Typical internal resistor values are 4.7 kΩ for both R1 (input/base) and R2 (emitter), with a ratio tolerance of ±20%. Total power dissipation is rated at 200 mW at 25°C ambient temperature. The component is AEC-Q101 qualified for automotive applications.
Feature Summary
- Integrates a PNP transistor with dual bias resistors to simplify circuit design and reduce component count.
- AEC-Q101 qualified for reliability in automotive environments.
- Compact SOT323 surface-mount package suitable for space-constrained designs.
Applications
- Digital applications in automotive and industrial segments
- Control of IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix /ZLX against official Nexperia documentation to confirm packaging details and manufacturing site codes. Ensure compatibility with standard reflow soldering processes as specified in the datasheet. Confirm availability through authorized distributors or Nexperia sales offices.
Selection Notes
Select this component when a compact PNP switching solution with integrated base and emitter biasing is required. The SOT323 package offers a small footprint compared to larger alternatives like SOT23. Consider the -50 V rating and 100 mA current capability for load switching tasks. Verify thermal requirements against the 200 mW dissipation limit in the target application environment.
Part Context
This part belongs to the PDTA143E series of PNP resistor-equipped transistors. Other variants in the series include PDTA143EE (SOT416), PDTA143EM (SOT883), and PDTA143ET (SOT23). The NPN complement for this family is the PDTC143 series. All variants share similar electrical characteristics but differ in package type and power dissipation ratings.
Replacement Considerations
Direct replacements within the same series include PDTA143ET (SOT23) or PDTA143EM (SOT883) if package changes are acceptable. For pin-compatible alternatives in different packages, verify resistor values and voltage ratings carefully. No other specific substitute part numbers are confirmed in the provided documentation.
