Gas Plasma Voltage Dependent Switches Switching Gas Discharge Tubes

The LT Series is a 2-terminal bi-directional, voltage triggered switch is designed for ignition circuits used in high pressure HID lighting. 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.

• Tape and reel to EIA 481-1

Applications

• For switching stored electrical energy (such as capacitive discharge) at predetermined voltages.

• Designed for ignition circuits used in high pressure HID lighting.
