Overview
The PDTD123EU-QX is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates a single NPN transistor with built-in bias resistors, specifically R1 and R2, both typically rated at 2.2 kΩ. The device is housed in a compact SOT-323 (SC-70) surface-mount package. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (Ic) of 100 mA. The component supports a maximum power dissipation of 200 mW and operates within a temperature range of -65°C to +150°C. It holds AEC-Q101 qualification for automotive applications.
Feature Summary
- Integrated bias resistors simplify circuit design and reduce component count
- AEC-Q101 qualified for automotive reliability standards
- Compact SOT-323 package suitable for high-density mounting
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver applications
Procurement Notes
Verify the specific suffix 'QX' against official Nexperia documentation to confirm it denotes the standard tape-and-reel packaging format rather than a variant with altered electrical characteristics. Ensure the procurement order explicitly references the full part number PDTD123EU-QX to distinguish it from non-qualified or differently packaged equivalents within the same product family.
Selection Notes
Select this component when an NPN digital transistor with 2.2 kΩ base and emitter resistors is required in a small SOT-323 footprint. It serves as a direct replacement for discrete resistor-transistor networks. Verify that the 100 mA collector current and 50 V voltage ratings meet the load requirements of the target application before finalizing the design.
Part Context
This part belongs to the PDTD1xxxEU series of NPN pre-biased transistors. It shares the same internal schematic and pinout as the standard PDTD123EU but carries additional automotive qualification certification. The 'QX' suffix indicates the specific reel packaging configuration used for automated assembly processes.
Replacement Considerations
The PDTB123EU-QX is the PNP complement within the same qualified series. For non-automotive contexts, the standard PDTD123EU may be considered if automotive qualification is not required.
