Overview
The PDTD123YU-QF is a single NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates an NPN bipolar junction transistor with two internal biasing resistors within a compact SOT-323 surface-mount package. The device is rated for a maximum collector-emitter voltage of 50 V and supports a continuous collector current of up to 500 mA. Internal resistor values are specified at 2.2 kOhms for both the base (R1) and emitter (R2) connections. The component features a transition frequency of 225 MHz and a maximum power dissipation of 300 mW. It holds AEC-Q100 qualification, indicating suitability for automotive applications.
Feature Summary
- Integrates NPN transistor with dual 2.2 kOhm biasing resistors in a single SMD package
- AEC-Q100 qualified for automotive-grade reliability requirements
- High-speed operation supported by 225 MHz transition frequency
- Designed for simplified circuit layouts through integrated pre-biasing
Applications
- Automotive logic level shifting circuits
- Switching applications in vehicle control modules
- Driver circuits for low-power loads in automotive environments
Procurement Notes
Verify the specific suffix 'QF' against official Nexperia documentation to confirm exact tape-and-reel specifications and packaging details. Ensure the procurement channel provides traceability to the manufacturer's original production lot. Confirm that the delivered components match the AEC-Q100 qualification status required for the intended application environment.
Selection Notes
Select this component when a design requires a single NPN switching element with fixed internal biasing resistors to reduce board space. The 50 V rating and 500 mA current capacity define the operational limits. Verify that the 2.2 kOhm internal resistance values align with the driving source capabilities and required switch speeds for the target circuit topology.
Part Context
This part belongs to the PDTD1zzzU series of Resistor-Equipped Transistors from Nexperia. These devices combine discrete transistor and resistor functions into one footprint. The 'Q' designation typically indicates automotive qualification under AEC-Q100 standards. The SOT-323 package offers a small form factor suitable for high-density PCB layouts common in modern electronic assemblies.
Replacement Considerations
Direct substitutes include other PDTD123 variants from Nexperia such as PDTD123EUF or PDTC123TU-QX, provided they meet the same electrical ratings and package constraints. Verify pinout compatibility and internal resistor tolerances before substitution.
