WebMar 14, 2024 · Three steps for choosing the correct flyback diode current rating. Choosing the right current setting is just as important as selecting the voltage rating. Overvoltage can destroy the internal P-N junction in the diode while overcurrent can result in the diode overheating. Step 1: Determine the average current rating and multiply by 10 WebThe voltage across the inductor is limited to the forward voltage of the diode, around 0.7 - 1.5V. This "freewheeling" or "flyback" current through the diode and inductor decreases slowly to zero as the magnetic energy in the inductor is dissipated as heat in the series resistance of the windings.
