DTD114EK is a digital transistor from ROHM with built-in resistors, and is used in inverter, interface and driver applications.
The DTD114EK is a digital transistor with built‑in bias resistors, intended for inverter, interface, and driver applications. Its integrated thin‑film resistors simplify circuit design by eliminating the need for external input resistors and reducing parasitic effects.
Key specifications include a 50 V supply rating, 500 mA output current, 200 mW power dissipation, and a transition frequency of 200 MHz. The device is supplied in an SMT3 package (taping code 7146) and is suitable for general‑purpose electronic equipment, but not for safety‑critical or radiation‑tolerant applications.
