DTD123YK is a digital transistor produced by ROHM. It features built-in bias resistors that allow you to configure an inverter circuit without connecting external input resistors. The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. Only the on / off conditions need to be set for operation, making the device design easy.
The DTD123YK is a digital transistor with integrated bias resistors, designed for inverter, interface and driver applications. Built‑in thin‑film resistors allow negative biasing and reduce parasitic effects, simplifying circuit design.
Key specifications include a 50 V supply rating, 500 mA output current, 200 mW power dissipation, and operation over a wide temperature range. Package information, absolute maximum ratings, and detailed electrical characteristic curves are provided for designers.
