Working Principle of 53D Disk Varistor
At low voltages, 53D Varistor has high resistance, which decreases significantly as the voltage increases. When a voltage surge occurs, the Disk varistor conducts current, shunting it away from sensitive components and thus protecting them from damage. The transition from high to low resistance is due to the breakdown of diode-like junctions formed at the boundaries of the ZnO grains. This rapid response protects the circuit from potential damage.
