Remember that the diode will need a Vf of above 0.6V before it switches on, and in the case of typical 1N400x series diodes is about 1.0V. There is also an issue with standard diodes with switching speed. Before it turns on, you will get a hefty negative spike that can destroy the switching circuit. WebFigure 5. Snubber Circuits. Figure 5 shows two different snubber circuits: a diode-Zener (DZ) snubber and a resistor-capacitor (RC) snubber. A snubber circuit works by absorbing excess energy due to the leakage inductance L l, thereby protecting the IC from potentially dangerous high voltages or excessive ringing.The DZ snubber ensures a well-defined …

talladega office machinesFlyback 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 … See more A 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 … See more When used with a DC coil relay, a flyback diode can cause delayed drop-out of the contacts when power is removed, due to the continued circulation of current in the relay coil and diode.
