Varistor As Flyback Diode at Roy Houston blog

Varistor As Flyback Diode. A common solution for suppressing relay coil bemf is to place a general purpose diode across the coil to serve as a shunt. The diode is oriented to block the source voltage during. The flyback diodes were too expensive to buy, and we had no other varistors here for these voltages required. Using a varistor or a combination of zener diode and a normal diode instead of just a single diode has following advantage: These are rated for various residential and. After turning off the coil of a relay the energy. Metal oxide varistors (movs) provide surge protection and maintain signal integrity in power circuits. The first link especially seems to push the option of varistors. So we ended up changing the ac valve with a dc one of 24v. Careful consideration of voltage rating, range, energy rating and maximum surge current value is essential when selecting an mov for optimal protection against voltage surges. They highlight a concern that flyback diode can. The commercial ac equivalent to a flyback diode is a quencharc which is a capacitor in series with a resistor rated for power line use.
