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
• RoHS compliant
• 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.
APPLICATIONs
• For switching stored electrical energy (such as capacitive
discharge) at predetermined voltages.
• Designed for in gas fuel ignition systems and similar circuits.
