The TNR7C330K-T varistor utilizes a metal oxide semiconductor material, which exhibits a non-linear voltage-current characteristic. When the voltage across the varistor exceeds its clamping voltage, its resistance rapidly decreases, diverting the surge current away from the protected components. This rapid clamping action effectively prevents the voltage from rising to damaging levels, thereby protecting the circuit.
