Product Description

Product Overview

The DTC623TU / DTC623TK are NPN digital transistors featuring built-in resistors, offering the advantages of regular digital transistors along with enhanced performance for specific applications. These transistors are designed with a low saturation voltage, typically VCE (sat) = 40mV at IC / IB = 50mA / 2.5mA, making them ideal for muting circuits. They also support high current levels, with IC up to 600mA. The devices are available in UMT3 (<SC-70>) and SMT3 (<SC-59>) packages.
