DTA143T series PNP -100mA -50V Digital Transistors (Bias Resistor Built-in Transistors) is a PNP transistor with built-in bias resistors, which can configure an inverter circuit without connecting external input resistors (see equivalent circuit).
The DTA143T series are PNP digital transistors that incorporate built‑in bias resistors, allowing inverter or switching circuits without external resistors. Variants such as DTA143TUB are offered in SOT‑416, SOT‑323 and other surface‑mount packages and are RoHS‑compliant.
The sheet provides absolute maximum ratings, electrical characteristics, dimension tables for each package, and application notes for switching, inverter and driver circuits. A notice at the end outlines usage restrictions and export requirements.
