EMA2 / UMA2N / FMA2A are three complex digital transistors produced by ROHM, which use built-in bias resistors and do not need to connect external input resistors to form an inverter circuit.
The document provides detailed information on ROHM's EMA2, UMA2N and FMA2A PNP transistors, which feature built‑in 47 kΩ bias resistors, emitter‑common configuration and RoHS compliance. It lists key features, internal circuit diagrams and typical application circuits.
Technical data include absolute maximum ratings, electrical characteristics, characteristic curves, package dimensions and ordering information. The datasheet also contains legal notices and guidance on proper use and export compliance.
