Overview
The PDTA143EE,115 is a PNP resistor-equipped transistor (RET) from the PDTA143E series, manufactured by Nexperia and distributed by NXP USA Inc. It integrates a PNP transistor with built-in bias resistors R1 (input) and R2 in a compact SOT416 (SC-75) surface-mounted package. The device features a collector-emitter voltage (VCEO) of -50 V and an output current capability of -100 mA. The typical input bias resistor R1 value is 4.7 kΩ, with a range of 3.3 to 6.1 kΩ. The total power dissipation is limited to 150 mW at an ambient temperature up to 25 °C, with a maximum junction temperature of 150 °C. This component is AEC-Q101 qualified for automotive applications.
Feature Summary
- Integrates a PNP transistor with built-in bias resistors to simplify circuit design and reduce component count.
- AEC-Q101 qualified for reliability in automotive environments.
- Offers a cost-saving alternative to discrete BC847/857 series transistors in digital switching applications.
Applications
- Digital applications in automotive and industrial segments
- Control of IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering code PDTA143EE,115 against the manufacturer's current product status to ensure availability. Confirm that the SOT416 package variant matches the design footprint requirements. Check for any recent revision history updates that may affect marking codes or electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component when a compact PNP switching solution with integrated base biasing is required. Ensure the application voltage does not exceed the -50 V collector-emitter rating. Consider the 150 mW power dissipation limit in the SOT416 package when designing thermal management strategies for high-duty cycle operations.
Part Context
The PDTA143EE belongs to the broader PDTA143E family of PNP resistor-equipped transistors. While other variants like PDTA143ET utilize the SOT23 package, the EE suffix specifically denotes the ultra-small SOT416 (SC-75) form factor. This family serves as a standardized replacement for general-purpose discrete PNP transistors in space-constrained PCB layouts.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should verify pinout compatibility and electrical parameters if considering cross-brand alternatives.
FAQ
What is the function of the internal resistors in the PDTA143EE?
The device includes built-in bias resistors: R1 acts as the input resistor connected to the base, and R2 is connected between the base and emitter. These eliminate the need for external discrete resistors in standard switching circuits.
What is the maximum power dissipation for the PDTA143EE in the SOT416 package?
The total power dissipation (Ptot) for the PDTA143EE is specified as 150 mW when mounted on an FR4 PCB at an ambient temperature of 25 °C or lower.
Is the PDTA143EE suitable for automotive applications?
Yes, the PDTA143E series, including the PDTA143EE, is qualified in accordance with the Automotive Electronics Council (AEC) standard Q101, making it suitable for automotive use.
