Switching Spark Gap
UN2K8 Series
UN2K8-XXXL
UN2K8-XXX
Description
The 2K8 series is a two-terminal, bi-directional, voltage triggered
switch, specifically for ignition circuits used in high pressure HID
lighting. The gas plasma trigger technology offers very fast switch
speeds with improved di/dt values compared to similar function
silicon based devices. Switching voltages are fixed depending on
the part number selected.
