The TNR5C271K-T varistor is constructed using 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 clamping action prevents the voltage from rising to damaging levels.
