Overview
The PDTA143ZU is a PNP Resistor-Equipped Transistor (RET) housed in an SOT323 (SC-70) surface-mounted plastic package. It integrates bias resistors R1 (4.7 kΩ) and R2 (47 kΩ) with a PNP transistor, offering a 100 mA output current capability and a collector-emitter voltage rating of -50 V. The device features a DC current gain (hFE) of 100 at -10 mA and a transition frequency (fT) of 180 MHz. Qualified under AEC-Q101 standards, it supports ambient temperatures from -65 °C to 150 °C with a total power dissipation of 200 mW at 25 °C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count
- Qualified for automotive applications according to AEC-Q101 standards
- Provides cost-saving alternative for discrete transistor configurations in digital applications
Applications
- Digital applications in automotive and industrial segments
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix matches the required packaging configuration before procurement. Confirm that the AEC-Q101 qualification status aligns with target automotive application requirements. Ensure the SC-70 package dimensions fit the designated PCB footprint. Cross-reference the marking code %47 with manufacturing site codes if traceability is required for quality assurance processes.
Selection Notes
Select this component when a compact PNP solution with integrated biasing is needed for digital switching or input control. The SOT323 package suits space-constrained designs. Verify that the -50 V collector-emitter voltage and 100 mA current ratings exceed maximum circuit stress levels. Consider the thermal resistance of 625 K/W for heat dissipation planning in enclosed environments.
Part Context
This part belongs to Nexperia's PDTA series of resistor-equipped transistors. The NPN complement is the PDTC143ZU. Both devices share similar electrical characteristics and package types but differ in polarity. The series is designed to replace discrete resistor-transistor combinations in digital logic interfaces.
Replacement Considerations
The PDTC143ZU serves as the NPN complement within the same family. Direct substitution requires verifying polarity compatibility with the existing circuit topology. Other RETs with different resistor values may require circuit redesign due to altered bias currents.
