ROHM EMB3 / UMB3N / IMB3A Datasheet
The EMB3, UMB3N, and IMB3A are PNP -100 mA -50 V complex digital transistors with built‑in bias resistors, allowing inverter circuits without external resistors. They feature thin‑film bias resistors with complete isolation and are lead‑free/RoHS compliant.
Key specifications include a collector‑base voltage of 50 V, a maximum collector current of 100 mA, and a junction temperature rating of 150 °C. The devices are offered in SOT‑353 (EMB3) and SOT‑457 (UMB3N, IMB3A) packages, with detailed dimensions and packaging data provided for PCB layout. Typical applications are inverter, interface, and driver circuits.
