Switching Gas Discharge Tubes

Gas Plasma Voltage Dependent Switches

The VS Series is a 2-terminal bi-directional, voltage triggered

switch designed for gas fuel ignition systems and similar circuits.

Switching voltages for the devices are fixed depending on the

part number selected. The gas plasma trigger technology offers

very fast switching speeds, resulting in significantly better di/dt

values when compared to silicon based SIDAC devices. Due to

the high switching voltage of the devices, step-up transformer

sizes and specifications can be reduced saving cost, size and

weight.

Features

Applications

RoHS

•

RoHS

Ceramic chamber for ultimate reliability.

Very high switching speed once switching voltage has

been reached, resulting in high di/dt to be generated

enabling the best performance to be extracted from

ignition transformers.

For switching stored electrical energy (such as capacitive

discharge) at predetermined voltages.

Designed for in gas fuel ignition systems and similar circuits.
