LT350A Datasheet, PDF (1/2 Pages) Littelfuse – Switching Gas Discharge Tubes

Switching Gas Discharge Tubes
Gas Plasma Voltage Dependent Switches
RoHS _{LT Series}
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.
