Overview
The PDTC143XK,115 is an NPN Resistor-Equipped Transistor (RET) from the PDTC143X series, manufactured by Nexperia. It integrates a single NPN transistor with built-in bias resistors in a surface-mounted device package. The component features a collector-emitter voltage of 50 V and an output current capability of 100 mA. The internal circuit includes a base resistor (R1) with a typical value of 4.7 kΩ and an emitter-base resistor (R2) with a typical ratio to R1 of 2.1. This configuration simplifies digital circuit design by reducing external component count.
Feature Summary
- Integrates NPN transistor with built-in bias resistors to reduce component count
- Simplifies circuit design for digital applications
- Suitable for automotive and industrial segments
- AEC-Q101 qualified for automotive reliability
Applications
- Control of IC inputs
- Switching loads
- Digital applications in automotive and industrial segments
Procurement Notes
Verify the specific package type associated with the 'K' suffix against official Nexperia documentation, as the provided datasheet revision history indicates that certain type numbers were removed or modified. Confirm the manufacturer source, noting that the NXP Standard Product business became Nexperia. Ensure the ordering code matches current production status before procurement.
Selection Notes
Select this component for designs requiring a compact NPN switching solution with integrated biasing. The 100 mA output current and 50 V rating suit general digital logic interfacing. Consider the thermal resistance characteristics relative to the specific SMD package used. Verify compatibility with AEC-Q101 requirements if deploying in automotive environments.
Part Context
The PDTC143XK,115 belongs to the PDTC143X family of NPN resistor-equipped transistors. This series offers cost-saving alternatives to standard discrete transistor pairs like the BC847/857 series. The 'K' designation typically refers to a specific package variant within the broader PDTC143X lineup, which includes packages such as SOT23, SOT323, and SC-70.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult official Nexperia documentation for equivalent RET devices with matching electrical parameters and package dimensions.
