Overview
The PDTC123EU-QX is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia, designed for surface-mount applications in the SOT-323 (SC-70) package. It integrates a single NPN bipolar junction transistor with internal biasing resistors to simplify circuit design and reduce board space. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current (Ic) of 100 mA, and a typical input base resistor (R1) value of 2.2 kΩ. The device operates within a temperature range of -65°C to +150°C and features a power dissipation rating of 200 mW. This component is qualified for automotive applications, ensuring reliability in demanding environments.
Feature Summary
- Integrates NPN transistor with built-in biasing resistors to minimize external component count
- Automotive-grade qualification ensures high reliability for vehicle electronics
- Compact SOT-323 surface-mount package optimizes PCB layout efficiency
Applications
- Switching applications in automotive electronic control units
- Driver circuits for low-power loads in industrial systems
- Logic level translation and buffer stages in communication interfaces
Procurement Notes
Verify the specific suffix 'QX' against official Nexperia documentation to confirm automotive grade status and tape-and-reel packaging details. Ensure compatibility with SOT-323 footprint requirements during procurement planning. Cross-reference RoHS compliance data sheets for environmental regulations. Confirm lead times and availability directly with authorized distributors as supply conditions may vary.
Selection Notes
Select this component when a compact NPN switching solution with integrated base resistance is required. The 2.2 kΩ internal resistor simplifies drive circuitry compared to discrete transistors. Verify that the 50 V voltage rating and 100 mA current capacity meet the load requirements. Consider the SOT-323 package size constraints and thermal dissipation limits of 200 mW for the specific application environment.
Part Context
This part belongs to the Nexperia PDTx series of Resistor-Equipped Transistors, which combine bipolar transistors with on-chip resistors. The 'PDTC' designation indicates an NPN configuration with a base resistor. The '-Q' suffix typically denotes automotive qualification under AEC-Q101 standards, distinguishing it from standard commercial variants within the same electrical family.
Replacement Considerations
Direct substitutes include other NPN RETs with similar 50 V, 100 mA ratings and SOT-323 packages, such as the PDTC123TU or PDTC123TT. Verify pinout compatibility and resistor values (R1=2.2kΩ) before substitution. Alternative manufacturers like ON Semiconductor or STMicroelectronics offer comparable parts, but ensure exact parameter matching for critical automotive applications.
