Overview
The PDTA143ZT-QR is a PNP Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates a single PNP transistor with built-in bias resistors R1 and R2 into a compact SOT-23 surface-mount package. The device supports an output current of 100 mA and withstands a collector-emitter voltage of -50 V. Internal resistor values are specified as R1 = 4.7 kΩ and R2 = 47 kΩ, yielding a nominal ratio of 10. Qualified under AEC-Q101 standards, it operates within a junction temperature range up to 150 °C and features a total power dissipation rating of 250 mW.
Feature Summary
- Integrates a PNP transistor with fixed internal bias resistors to reduce external component count
- Qualified according to AEC-Q101 automotive standards for reliability in demanding environments
- Designed for simplified circuit design through reduced pick-and-place costs
Applications
- Digital applications in automotive and industrial segments
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific suffix 'QR' against the manufacturer's official ordering information to confirm reel packaging specifications and manufacturing site codes. Ensure that the selected variant matches the required AEC-Q101 qualification status for your target application environment. Cross-reference the datasheet revision date to confirm the most recent product data sheet is being utilized for design validation.
Selection Notes
Select this component when a PNP switching solution with integrated base biasing is required to minimize board space and assembly complexity. The SOT-23 package is suitable for standard surface-mount processes. Verify that the 100 mA current capability and -50 V voltage ratings align with the load requirements. Consider the thermal resistance characteristics if operating near maximum ambient temperatures.
Part Context
This part belongs to the PDTA143 series of PNP resistor-equipped transistors from Nexperia. It serves as a digital alternative to discrete BJT configurations, offering a pre-biased solution for logic interfacing. The 'ZT' designation indicates the specific resistor values and SOT-23 package type within the broader family of RET products designed for general-purpose switching and amplification tasks.
Replacement Considerations
PDTC143ZT-Q is the NPN complement within the same series. PDTA143TT-Q is another PNP variant in the same series but may differ in specific marking or secondary packaging details.
