ZVX Series
Low Energy, Low Capacitance SMD Varistor
Stackpole Electronics, Inc.
Resistive Product Solutions
Description:
The ZVX Series are low-energy (0.1 joules) varistor chips, designed specifically
for the protection of I/O line drivers and other sensitive semiconductor gates from
the damaging effects of high voltage, low-energy transients such as ESD events.
Unlike other competitive low-energy varistors, the ZVX Series offers all the
protection features of standard varistor chips, and exceptionally low values of
capacitance. In these applications, as the frequency of data transfer increases,
lower capacitance is required to eliminate possible skewing of the data signals
due to capacitive loading.
In most cases, the 1KHz capacitance values of the ZVX Series are less than one half that of the competition. Further,
this series is offered in 0603, 0805 and 1206 sizes, with an expanded range of voltages from 3V to 38Vdc.
Features:
•
•
•
•
•
•
•
•
•
AC operating voltage (Vrms) from 2V to 30V
DC operating voltage (Vdc) from 3V to 38V
Bi-directional, low clamping voltages
Exceptionally low capacitance ratings
3 model sizes available 0603, 0805, 1206
+125ºC continuous operating temperature
Dimensional and weight savings on PC board
AgPd end terminations
Non-coated chips guarantee excellent
flammability rating
Applications:
•
•
•
ESD protection for components sensitive to IEC
1000-4-2, MIL-STD 883C Method 3015.7 and
other industry specifications
Excellent for I/O line protection, operating at high-
speed data transfer rates, due to very low
capacitance values
Replaces larger surface mount TVS diodes in
many applications
