Flayback diode
WebInductive Flyback and Flyback Diodes Introduction Inductive flyback refers to the voltage spike created by an inductor when its power supply is suddenly reduced or removed. This voltage spike occurs because the current flowing through the inductor cannot change instantly. The rate at which the current can change is limited by the inductor's time constant.

WebSep 27, 2010 · Sep 24, 2010. #12. The flyback voltage from a switched inductor does not appear on the supply rail. It appears on the switched side of the inductor. Also, the protection diode peak current will not exceed the magnitude of the current that was flowing through the inductor when it was switched off. J. WebMay 6, 2024 · Putting them at the transistor is OK . . . If the cable connecting the driver and inductive load is short this will work. However if the cable is long, place the diode at the load as there can be noise induced in adjacent wiring. Besides, the load is usually a convenient is place to put the diode.
