Overview
The PDTA143EK,115 is a PNP resistor-equipped transistor manufactured by NXP USA Inc. It integrates two bias resistors within a single SOT-23 (TO-236AB) surface-mount package to simplify circuit design. The device features a collector-emitter voltage rating of 50 V and a maximum DC output current of 100 mA. Internal resistance values are specified as R1 = 4.7 kΩ and R2 = 4.7 kΩ, maintaining a ratio of 1. Key electrical characteristics include a minimum DC current gain (hFE) of 30 at -10 mA collector current and a maximum collector-emitter saturation voltage of 150 mV under standard test conditions.
Feature Summary
- Integrates built-in bias resistors to reduce component count
- Simplifies circuit design for switching and amplification
- Reduces pick and place costs in manufacturing
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and marking code. Ensure compatibility with the required thermal management specifications for the target application environment. Cross-reference the datasheet revision date to confirm the validity of the electrical parameters provided.
Selection Notes
Select this component when space constraints require a compact solution for PNP switching tasks. The integrated resistor network eliminates the need for external biasing components, reducing board area. Verify that the 50 V voltage rating and 100 mA current capacity meet the system requirements before finalizing the design.
Part Context
This part belongs to the PDTA143E series of PNP resistor-equipped transistors produced by Philips Semiconductors, now NXP. The series includes various package options such as SOT323, SOT346, and SOT883. The PDTA143EK specifically utilizes the SOT-23 package format, providing a standardized footprint for surface-mount assembly processes.
Replacement Considerations
The PDTC143EK serves as the NPN complement within the same product family. Designers requiring an NPN configuration should consider this alternative. Other packages in the series may offer physical interchangeability depending on the PCB layout constraints.
