WebOn-off ratio is the ratio of the on-state and off-state current without any applied gate voltage (Vg). A high on-off ratio means a low leakage current i.e. an improved device performance. Web8 aug. 2024 · The on-resistance of a Mosfet increases as it heats up so yours might be 0.01 ohms at the 10A current. Simple math shows 10A into 0.01 ohms= 1W but 50% switching causes only 0.5W. But the Mosfet heats much more if the on and off switching is slow since it will be linear and getting hotter.
