Varistor Specification
TYEE Varistor
Varistor are voltage dependent, nonlinear device which have an
electrical behavior similar to back-to-back zener diodes.
TYEE series zinc oxide varistor are nonlinear resistors, consisting
main of zinc oxide and several kinds of metal oxide additive.
They are bilateral and symmetrical V-I characteristics curve and
unparalleled large peak current capability are used for absorption
of transient voltage, suppression of pulse noise and circuit
voltage stabilization.

Selection guide
1.Determine the necessary steady-state voltage (working voltage).
2.Establish the transient energy absorbed by the varistor
3.Calculate the peak transient current through the varistor
4.Determine power dissipation requirement.
5.Select a model to provide the required voltage-clamping characteristics
