In one example in accordance with the present disclosure, a fluid ejection device is described. The fluid ejection device includes a number of nozzles to eject an amount of fluid. A first field-effect transistor (FET) activates a first fluidic operation component and a second FET activates a second fluidic operation component. The first FET and the second FET are selected from among a high-side switch FET, a low-side switch FET, and a hybrid FET and the first FET and the second FET are different from one another.
