PDTD123EUF

Overview

The PDTD123EUF is an NPN Resistor-Equipped Transistor (RET) from the PDTD1xxxU series, manufactured by Nexperia USA Inc. It integrates a transistor with built-in bias resistors in a SOT323 (SC-70) surface-mounted package. Key electrical parameters include a collector-emitter voltage of 50 V, an output current capability of 500 mA, and a maximum power dissipation of 300 mW at 25 °C. The device features a base resistor (R1) of 2.2 kΩ and an emitter-base resistor (R2) of 2.2 kΩ. It has a transition frequency of 225 MHz and meets AEC-Q101 qualification standards for automotive applications.

Feature Summary

• Integrates bias resistors to simplify circuit design and reduce component count
• Qualified for high-temperature applications up to 175 °C junction temperature
• AEC-Q101 qualified for automotive reliability
• Provides ±10% resistor ratio tolerance

Applications

• IC inputs control
• Switching loads
• Cost-saving alternative to BC807 or BC817 series transistors in digital applications

Procurement Notes

Verify the specific suffix 'F' against the official datasheet, as standard documentation lists 'EU'. Confirm RoHS compliance and REACH status directly with the manufacturer or authorized distributors. Ensure the ordering information matches the exact package configuration and marking code required for your assembly process.

Selection Notes

Select this component when a compact NPN switching solution with integrated biasing is required. The 2.2 kΩ resistor values are suitable for general-purpose logic interfacing. Consider the thermal resistance characteristics if operating near the 175 °C limit. Verify that the 500 mA current rating meets the load requirements of the specific application.

Part Context

This part belongs to the PDTD1xxxU series of NPN resistor-equipped transistors. It shares the same SOT323 package and core transistor characteristics with variants like PDTD113EU and PDTD143EU, differing primarily in the internal resistor values. The PDTD123YU is a related variant with different R2 values.

Replacement Considerations

PDTD123YU is a direct functional substitute within the same series, sharing the same package and R1 value but featuring a different R2 value (10 kΩ vs 2.2 kΩ). Designers must verify if the change in the base-emitter resistor affects the specific circuit operation before substitution.
