This document describes the features and characteristics of ROHM's DTC114Y series NPN digital transistors, including built-in bias resistors that enable the configuration of an inverter circuit without external input resistors. The bias resistors consist of thin-film resistors with complete isolation, eliminating parasitic effects. Only the on/off conditions need to be set for operation, making circuit design easy. The transistors are suitable for switching circuits, inverter circuits, interface circuits, and driver circuits.
The DTC114YUB is an NPN 100 mA 50 V digital transistor with built‑in bias resistors, allowing inverter or switching circuits without external resistors. The device includes thin‑film bias resistors for isolation and negative biasing, and it is RoHS‑compliant.
The datasheet lists absolute maximum ratings, electrical characteristics such as supply voltage, input voltage range, output current, and transition frequency, as well as detailed package dimensions for the SOT‑416 (SC‑75A) form factor. Application examples include switching, inverter, interface, and driver circuits.
