EMF5 Transistors Rev.A 1/4 Power management (dual transistors) EMF5 2SA2018 and DTC144EE are independently housed in an EMT6 package. The product is a power switching circuit for power management, with the features of reduced mounting cost and area.
The EMF5 is a power‑management component that integrates two independent transistors (2SA2018 and DTC144EE) in a single EMT6 package. It is intended for use in power‑switching circuits where reduced mounting cost and board area are desired.
The document lists the device's packaging dimensions, absolute maximum ratings, electrical parameters such as transition frequency, breakdown voltages, and DC current gain, as well as characteristic curves. It also includes application notes, usage warnings, and contact information for ROHM support.
