EMH15 / IMH15A are NPN complex digital transistors produced by ROHM Co., Ltd. They have built-in bias resistors. They can be used in inverter circuits, interface circuits, and driver circuits. They have built-in bias resistors, eliminating the need for external input resistors and making it easy to configure inverter circuits. Only the on/off conditions need to be set for operation, simplifying circuit design.
The EMH15 and IMH15A are NPN 100 mA, 50 V digital transistors that incorporate built‑in bias resistors, allowing inverter or driver circuits without external bias components. Each package contains two DTC144T chips and is RoHS‑compliant, making circuit design simple and reliable.
The datasheet lists absolute maximum ratings, detailed electrical characteristics, and mechanical dimensions for the SOT‑457 (EMH15) and SC‑74 (IMH15A) packages, along with typical application circuits such as inverters and interface drivers.
