What is the use of a piezoresistor?The biggest characteristic of the piezoreductor is that when the voltage applied to it is lower than its threshold "UN", the current flowing through it is very small, equivalent to a closed valve. When the voltage exceeds UN, the current flowing through it surges, equivalent to the valve opening.Using this function, the abnormal overvoltage which often appears in the circuit can be suppressed to protect the circuit from the damage of overvoltage.Now we domestic color television, for example, the power supply circuit is used in the zinc oxide varistor, used here piezoresistive pressure sensitive voltage is 470 v, when the maximum transient surge voltage (RMS) of more than 470 v, varistor is reflected his clamping characteristics, the high voltage, low level after circuit in a safe working range.

2. Functions and applications of varistorsVaristors are widely used in household appliances and other electronic products. They are used for over voltage protection, lightning protection, surge current suppression, peak pulse absorption, amplitude limiting, high voltage arc suppression, noise elimination, semiconductor components protection, etc.
