TransGuard®
Multilayer Ceramic Transient Voltage Suppressors
GENERAL DESCRIPTION
TransGuard® multilayer varistors are zinc oxide (ZnO) based ceramic semiconductor devices with non-linear voltage-current
characteristics (bi-directional) similar to back- to-back zener diodes. They have the added advantage of greater current and
energy handling capabilities as well as EMI/RFI attenuation.
The increasing use of electronics technologies in all areas require reliable protection against transient voltages that could
damage the electronics circuitry as well as EMI/RFI attenuation to prevent signal distortion and to meet regulatory requirements.
AVX TransGuard components help achieve both functions with single component.
