Working Principle

TVS diodes operate on a basic principle of providing a low resistance path for transient overvoltage events in order to conduct excess current away from sensitive components. Generally, the protective diode will draw excess current to ground and dissipate the excess energy through the diode. When the voltage surge is greater than the diode\'s clamping voltage, the diode activates, providing a low-resistance current path and discharging the excess energy. This will reduce the voltage surge across the protected circuit, protecting it from damage.
