Overview
The PDTA143EU,115 is a PNP Resistor-Equipped Transistor (RET) from the PDTA143E series, manufactured by Nexperia. It integrates bias resistors within a single SOT-323 (SC-70) surface-mounted package to simplify circuit design and reduce component count. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, an output current (IO) of -100 mA, and a total power dissipation (Ptot) of -200 mW at 25°C ambient temperature. The typical input bias resistor (R1) is 4.7 kΩ with a ratio (R2/R1) of 1. The device operates within a junction temperature range up to 150°C and features a thermal resistance (Rth(j-a)) of 625 K/W.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce pick-and-place costs.
- Qualified for automotive applications in accordance with AEC-Q101 standards.
- Provides a cost-saving alternative to discrete BC847/857 series transistors in digital applications.
Applications
- Digital applications in automotive and industrial segments
- Control of IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details and manufacturing site codes. Confirm RoHS compliance status through the manufacturer's latest product data sheet or authorized distributor channels before finalizing procurement specifications.
Selection Notes
Select this component when a compact PNP transistor solution with integrated base biasing is required for space-constrained designs. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that the thermal environment supports the specified power dissipation limits for the SOT-323 package.
Part Context
This part belongs to the PDTA143E series of PNP resistor-equipped transistors. The 'EU' designation specifically identifies the SOT-323 (SC-70) plastic surface-mounted package variant. The series includes other package options such as SOT416, SOT883, and SOT23, all sharing similar electrical characteristics but differing in physical dimensions and thermal properties.
Replacement Considerations
For equivalent functionality in the same SOT-323 package, consider the PDTC143EU, which serves as the NPN complement within the same family. Verify pinout compatibility and electrical ratings against the target application requirements before substitution.
FAQ
What are the values of the internal bias resistors?
The typical input bias resistor (R1) is 4.7 kΩ, and the emitter-base resistor (R2) is also typically 4.7 kΩ, resulting in a standard R2/R1 ratio of 1.
Is this component suitable for automotive use?
Yes, the PDTA143E series has been qualified in accordance with the Automotive Electronics Council (AEC) standard Q101, making it suitable for automotive applications.
What is the maximum operating junction temperature?
The maximum junction temperature (Tj) for the PDTA143EU is 150°C.
