Radial Lead Varistors > ZA Series

Phenolic Coating Option -- ZA SeriesVaristors for Hi-

Temperature Operating Conditions:

Copper Electrode Option:

•

Add 'W' to the end of the part

number (e.g. V240ZA05PW)

•

Phenolic coated ZA Series devices are available with

improved maximum operating temperature of 125°C

Copper electrode option is only available

for V240~V750 for ZA series.

These devices also have improved temperature

cycling performance capability

Product marking:

Current Energy and Power Dissipation Ratings

device. The operating values of a MOV need to be derated

at high temperatures as shown above. Because varistors

only dissipate a relatively small amount of average power

they are not suitable for repetitive applications that involve

substantial amounts of average power dissipation.

Should transients occur in rapid succession, the average

power dissipation is the energy (watt-seconds) per pulse

times the number of pulses per second. The power so

developed must be within the speciﬁcations shown on the

Device Ratings and SpeciﬁcationsTable for the speciﬁc
