DTC144EK TD T146 – ROHM

The Rohm DTC144EK TD T146 is a digital transistor (BRT) featuring a built-in bias resistor network for simplified circuit design. This NPN transistor integrates a 47kΩ input resistor and a 47kΩ resistor between base and emitter, eliminating the need for external components and reducing board space. Its primary function is to provide a pre-biased switching solution, ideal for applications where direct microcontroller control is desired. The voltage rating is 50V, and the maximum output current rating is 100mA. Supplied in a small SOT-346 SMD package, the DTC144EK TD T146 offers a low profile and is suitable for high-density circuit boards. It’s commonly used in digital circuits for inverter stages, load drivers, and switching applications. Its operating temperature range is –55°C to 150°C. The integrated resistor network provides stable operation and reduces the risk of component mismatch, enhancing overall circuit reliability.
