DTA144WE / DTA144WUA / DTA144WKA are digital transistors with built-in resistors. It can be used for applications such as inverters, interfaces, and drivers.
The DTA144WUA is a -100 mA / -50 V digital transistor that includes built‑in thin‑film bias resistors, allowing inverter circuits without external resistors. Its compact SOT‑416/SC‑70 package enables high mounting density and easy circuit design.
The sheet lists absolute maximum ratings, typical electrical characteristics, and example application circuits. It also contains packaging details, dimension data, and a notice about usage restrictions and non‑radiation‑tolerant design.
