ϭ DEFINITION OF TECHNICAL TERMS
07D Series
Zine Oxide Varistor
Varistor Voltage(breakdown voltage):
The varistor voltage is the voltage across the varistor measured at a specified current lc(0.1mA or 1mA)
of specified duration.
Max. allowable Voltage and leakage current The maximum operating voltage corresponds to the
"rest"state of the varistor. Thi "srest” voltage offers a low leakage current in order to limit the power
consumption of the protective device and not to disturb the circuit to be protected. The leakage currents
usually have values in the range of a few micro-amperes.
ϥ Non linear exponent ( ):
The varistor voltage-current characteristic is defined by the equation:
l=KV ,where K is a constant dependent on geometry, and is the non linear exponent.
We usually take two points(V1,l1),(V2,l2 ) to estimate the value of . in which l1 and l2 are the current value
corresponding to the voltage value V1 and V2
Rated power:
The maximum power that can be applied within the specified ambient temperature.
Capacitance:
The capacitance of varistor is the reference value measured between the varistor terminals at specified frequency.
Withstanding surge current:
Withstanding surge current is the maximum peak current for the varistor with the specified standard impulse
current(8x20 sec) applied one time or two times and corresponding to a permissible
variation of 10% in the varistor voltage change.
Maximum clamping voltage:
Maximum clamping voltage is the maximum voltage Vp between two terminals with the specified standard impulse
current l (8x20 sec). The voltage value is an indication on the protective function of the varistor.
Energy
Maximum energy from one or a burst of pulses. It is the value within the varistor change of 10% when one impulse
of 10x1000 sec is applied.
E=KxVmxImxT
E:Energy
K:constant=1.4
Vm: Max. clamping voltage at Im.
Im: Max. allowable single surge current of 10x1000 sec.
T: Duration of surge current(1000 sec)
Pulse Iife time rating
This is expressed as the maximum allowable number of
impulse currents applied.8x20 sec impulse current
(or 10x1000 sec) is applied at prescribed interval.
(or 10x1000 sec) is applied at prescribed interval.
This curve also provides for derating current as required with
repetitive pulsing.
