Flyback diodes are commonly used when inductive loads are switched off by semiconductor devices: in relay drivers, H-bridge motor drivers, and so on. A switched-mode power supply also exploits this effect, but the energy is not dissipated to heat and instead used to pump a packet of additional charge into a capacitor, in order to supply power to a load. When the inductive load is a relay, the flyback diode can noticeably delay the release of the rela… WebThe flyback diode, however, is not a type of diode but rather a diode application. A flyback diode protects circuit components in circuits with changing magnetic fields. Let's look at …
