Flyback diode wikipedia
WebA flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted. It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters .

If the coil is switched off, a back EMF current will flow through the flyback diode. I can imagine that a flyback diode can have a smaller maximum current rating because the back EMF current doesn't last that long. What I would like to know:
WebNov 24, 2016 · A flyback diode serves to protect your circuitry from this effect. Because diodes have a forward voltage well under the thousands of volts generated by the inductive spiking, the extra power from the collapsing field instead goes through the flyback diode. WebIt is equivalent to a flyback converter using a single inductor instead of a transformer. [1] Two different topologies are called buck–boost converter. Both of them can produce a range of output voltages, ranging from much larger (in absolute magnitude) than the input voltage, down to almost zero.
WebAug 12, 2013 · The clamp diode is normally reversed biased but when there is an opposite current flowing it will protect the power supply as well as other components in the circuit. The negative voltage will be connected to the power supply but since the switch is opened on the positive side, no current will flow. The second illustration is a bit more confusing. The schematic of a flyback converter can be seen in Fig. 1. It is equivalent to that of a buck-boost converter, with the inductor split to form a transformer. Therefore, the operating principle of both converters is very similar: • When the switch is closed (top of Fig. 2), the primary of the transformer is directly connected to the input voltage source. The primary current and magn…
