EMH9 / UMH9N / IMH9A is a double NPN 100mA 50V complex digital transistor produced by ROHM. It has built-in bias resistors, external connection external input resistors, and has the advantage of completely eliminating parasitic effects.
The IMH9A is a 100 mA, 50 V NPN transistor that incorporates built‑in biasing resistors, allowing inverter or driver circuits without external resistors. The device is supplied in an SMT6 2928 package and is lead‑free/RoHS compliant.
The datasheet provides absolute maximum ratings, electrical characteristics, characteristic curves, and detailed mechanical dimensions for the IMH9A and related part numbers (EMH9, UMH9N). Legal notices and usage guidelines are included at the end of the document.
