EMD30 is a dual digital switch launched by ROHM. It has the characteristics of high withstand voltage, low resistance and low power consumption. It can be widely used in DC/DC converters and motor drivers.
The EMD30 is a general‑purpose isolated transistor offered by ROHM. It is supplied in an EMT6 package and is intended for use in DC/DC converters and motor driver circuits. The device includes both PNP (DTr1) and NPN (DTr2) digital transistors and can be mounted with EMT3 automatic mounting machines.
The document lists absolute maximum ratings, electrical characteristics, and characteristic curves for both DTr1 and DTr2, covering supply voltage, input voltage, output current, power dissipation, junction temperature, and storage temperature. Packaging details, external dimensions, and equivalent circuit information are also provided.
