I have a question on inductive kickback. To my understanding whenever you have an inductive load, you need to place in parallel a snubber diode, to provide a discharging path to the inductor's current one the supply is switched of. The time constant of this process will be given by the inductance of the inductor and the total resistance it sees (diode + inductor resistance). For almost all the applications usually one wants to reduce the discharge time to achieve fast OFF state. The question is, how could I slow down the de-magnetization process? Adding a resistance in series to the diode would increase the time constant but also will require to dissipate o lot of power because of the built in voltage of the inductor.

Thanks a lot for the hints
