DTB123EK is a digital transistor produced by ROHM with built-in bias resistors, which can be used to form an inverter circuit without connecting external input resistors.
The ROHM DTB123EK is a -500 mA / -50 V digital transistor with built‑in thin‑film bias resistors, enabling inverter circuits without external resistors. The device features complete isolation of the bias network, reducing parasitic effects and simplifying design.
The sheet provides packaging details (SMT3, Taping), absolute maximum ratings, electrical characteristics, and typical application circuits. It also includes legal notices and contact information for further product details.
