FAQ about TVS - Varistors, MOVs
-
1. What are Movs?
Movs(Move String) is an instruction cluster in assembly language, mainly used to copy strings. The Movs instruction cluster includes multiple variants for handling data movement operations of different lengths.
Basic Functions
The main function of the Movs instruction is to copy the data of the DSSI address to the ESDI address. Specifically:
MOVSB: Move one byte at a time.
MOVSW: Move one word (usually two bytes) at a time.
MOVSD: Move one double word (usually four bytes) at a time.

2. What is the use of MOV varistor?
MOV varistor (Metal-Oxide Varistor, referred to as MOV) is mainly used for overvoltage protection, especially in the fields of power electronics, communication electronics and industrial control.
Main use
Overvoltage protection: MOV varistors play the role of overvoltage protection in the circuit. They can quickly reduce their resistance value when voltage spikes or surges occur, thereby consuming surge energy and protecting other components in the circuit from damage.
Electrostatic protection: MOV varistors are often used for electrostatic protection, especially at the power input end, which can effectively prevent static electricity from damaging the circuit.
Lightning protection: By suppressing the surge voltage caused by lightning strikes, the equipment is protected from lightning strikes. -
3. What is the difference between TVS diodes and varistors?
The main differences between TVS diodes and varistors are in working principles, response time, current carrying capacity, nonlinear characteristics, capacitance effects, reliability and life, and application scenarios.
Working principle:
TVS diode (ransient voltage suppressor) is a high-efficiency protection device in the form of a diode. When both ends are subjected to instantaneous high-energy impact, the TVS diode can quickly change the impedance value from high to low, absorb large current, and clamp the voltage to a predetermined value.
Varistors use their nonlinear characteristics to sharply reduce resistance when the voltage exceeds a certain threshold, thereby absorbing surge current.
Response time:
The response time of TVS diodes is very fast, usually at the sub-nanosecond level (ps level).
The response time of varistors is relatively slow, usually at the nanosecond level (ns level).
Current carrying capacity:
Varistor can withstand larger surge currents. The larger the volume, the greater the surge current it can withstand, which can reach tens of kA to hundreds of kA.
The current carrying capacity of TVS diodes is relatively small.
Nonlinear characteristics:
The nonlinear characteristics of TVS diodes are similar to those of voltage-stabilizing diodes. The leakage current is very small before breakdown, and it has standard voltage-stabilizing characteristics after breakdown.
The nonlinear characteristics of varistors are poor, with a higher limiting voltage at high currents and a larger leakage current at low voltages.
Capacitive effect:
The capacitance of TVS diodes and varistors is large, but TVS diodes also have low-capacitance products, which are suitable for the protection of high-speed signal lines.
Reliability and life:
TVS diodes have high reliability, are not easy to deteriorate, and have a long service life.
Varistors have poor reliability, are prone to aging, and have a short service life.
