The DTA043Z series is a PNP type digital transistor from ROHM, which has built-in bias resistors to realize inverter circuits without connecting external input resistors. The transistor also features completely isolated thin-film resistors for negative biasing inputs and the elimination of parasitic effects.
The DTA043Z series digital transistors from ROHM feature built‑in bias resistors that simplify inverter and switching circuit designs. The series includes variants DTA043ZM, DTA043ZEB and DTA043ZUB, all RoHS‑compliant and available in standard surface‑mount packages.
The document provides absolute maximum ratings, detailed electrical characteristics, characteristic curves, and mechanical dimensions for each package type. It also includes application notes and packaging specifications for designers.
