Switching Gas Discharge Tubes
Gas Plasma Voltage Dependent Switches
RoHS
XT Series
The XT Series is a 2-terminal bi-directional, voltage triggered
switch designed for Xenon HID 'hot re-strike' circuits such as
those found in automobiles. 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
? 2 terminal configuration.
? 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.
? High lifetime and stability.
? Switching performance is virtually unaffected by changes
in ambient temperature.
? Tape and Reel to EIA 481-1
Applications
? This product is optimised for Xenon HID ‘Hot re-strike’
circuits which require a very high number of operations
at high current levels. The switching time is typically
10nS for the best possible efficiency .
