Maximum allowable continuous AC/DC voltage(VAC/VDC):

It refers to the voltage ampere (I-V) characteristic of positive and negative symmetry of the varistor, which can be applied to both DC and AC circuits. The maximum continuous working voltage refers to the maximum DC voltage VDC or maximum AC voltage effective value VRMS that the varistor can withstand for a long time during application.

Breakdown voltage(VB):

When a pulse current with a specified duration (usually 1mA and a duration generally less than 400mS) is passed through a varistor The voltage value at both ends.

Maximum allowable clamping voltage (Vc):

The highest voltage that a voltage sensitive resistor can withstand at both ends of a pulse peak current Ip=1A (8 * 20us). It indicates that in the specified.
The voltage generated by the impulse current Ip passing through the secondary terminals of the varistor is also known as residual voltage, so the selected varistor
The residual voltage must be less than the withstand voltage level Vc of the protected object, otherwise reliable protection cannot be achieved.

Maximum peak current (8/20 μ s) Weighing flow rate:

It refers to the allowable passage of a varistor under specified conditions (specified time interval and frequency, applying standard impulse current)
The maximum pulse (peak) current value on the device. If the current value exceeds the current capacity, the varistor will be damaged.

Leakage current at VDC leakage current is also called waiting current (ILDC):

It refers to the current flowing through the varistor at the specified temperature and maximum DC voltage, generally in uA level ,
if the leakage current is too large , it will cause heat damage and affect the abnormal operation of the system.

Non-linear coefficient nonlinear coefficient (α):

Nonlinear index α is a sign of whether the resistance value of a component changes with voltage or current and whether the change is sensitive, and the voltage-current characteristics of its piezoresistor and I = KVα approximate. K is a constant, and α is a voltage nonlinear coefficient (α coefficient).

Typical capacity value measured at 1KHz Capacity (PF):

The static capacity of a varistor refers to the inherent capacitance capacity of the varistor itself, which is generally expressed as a typical value, unless there is a special indication of the error range.

Load Dump energy:

It refers to the energy flowing through a varistor at a specified voltage (Us), time (Td), and impedance (Ri), usually expressed in joules (J).

Jump start voltage:

The process of starting a motor vehicle (most commonly a car or truck) with a dead or depleted battery. Refers to the voltage at which the varistor can continue to work after the specified voltage (Ujump) is activated, and the general time is defined as 1~5 (minutes).
