Product Overview

The DTC363EU/DTC363EK/DTC363ES are NPN digital transistors with built-in resistors, offering the advantages of regular digital transistors. They are particularly optimized for muting circuits due to their low V_O(on) (40mV typ. at I_O/I_I = 50mA/2.5mA) and can handle high currents up to I_C=600mA. These transistors are suitable for general electronic equipment and devices.
