ZVHT SMD Series - Low Voltage, High Temperature Varistors
General Information
Multilayered Varistor Symbol
The ZVHT series of low voltage multilayered varistors is designed to protect sensitive
electronic devices against high voltage surges in the low voltage region. They offer
excellent transient energy absorption due to improved energy volume distribution and
power dissipation. Low voltage varistors cover a wide DC operating voltage range
from 3 V to 170 V.
U
In addition, the ZVHT series exhibits independent suppression characteristics
enabling stable protection over a wide temperature range of -55 to +150 °C.
ZVHT series varistors are typically applied to protect integrated circuits and other
components at the circuit board level.
