The DTC143X series are NPN type 100mA, 50V digital transistors with built-in bias resistors, which allow the configuration of an inverter circuit without connecting external input resistors. These products have high reliability and high integration, and are suitable for various switching circuits, complementary driving circuits, interface circuits and driver circuits.
The DTC143X series from ROHM are NPN digital transistors that integrate a bias resistor, allowing inverter or driver circuits to be built without external resistors. The devices are lead‑free and RoHS compliant and are offered in several surface‑mount packages such as SOT‑416, SOT‑323, and SOT‑346.
Key specifications include a maximum collector‑emitter voltage of 50 V, a continuous output current of 100 mA, and built‑in thin‑film bias resistors of 4.7 kΩ or 10 kΩ. Electrical characteristic curves, absolute maximum ratings, and detailed mechanical dimensions for each package are provided in the sheet.
