DTA124TM/DTA124TE/DTA124TUA/DTA124TKA is a digital transistor launched by ROHM, with a rated current and power consumption of -100mA/-50V. It can be used in inverters, interfaces, drivers and other applications. The product has the following features: 1. The built-in circuit enables the configuration of an inverter circuit without connecting external input resistors. 2. The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input. 3. Only the on/off conditions need to be set for operation, making the device design easy.
The DTA124TUA is a -100 mA / -50 V digital transistor with built‑in thin‑film resistors, designed for inverter, interface and driver applications. Its PNP epitaxial planar silicon structure provides isolated bias resistors and simplifies circuit design.
The document provides detailed electrical characteristics, absolute maximum ratings, packaging options (VMT3, EMT3, UMT3, SMT3) and typical application circuits. It also includes legal notices and contact information for ROHM.
