The DTA143Z series is a PNP digital transistor that integrates a bias resistor and can be configured as an inverter circuit without connecting an external input resistor. The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of completely eliminating parasitic effects. Only the on/off conditions need to be set for operation, making the circuit design easy.
The DTA143ZUB is a PNP digital transistor with built‑in biasing resistors, designed for switching, inverter, interface and driver circuits. The datasheet lists its absolute maximum ratings, electrical characteristics, and mechanical dimensions for various package types.
Key specifications include a supply voltage rating of –50 V, output current of –100 mA, and power dissipation up to 200 mW. Package options such as SOT‑416, SOT‑323, and SOT‑346 are detailed with pin‑out diagrams and dimension tables. Application notes and a legal notice conclude the document.
