HIGH ENERGY SPARK GAP DEVICES

TG Legacy Series

VOLTAGE RANGES

APPLICATIONS

FEATURES

CP Clare's TG Legacy Series of two electrode sparkgaps excel in applications that require the efficient transfer of
high voltage, high energy pulses and DC overvoltage protection for magnetrons, diodes, capacitors, etc. The TG
Legacy Series also includes three electrode triggered sparkgaps (cold cathode thyratrons) for switching high
levels of stored energy in fractions of a microsecond, on command, using low energy control pulses.

Tight DC breakdown voltage tolerance (

10%)

Long-life tungsten or molybdenum electrodes

Rugged ceramic-to-metal or glass-to-metal
construction

gap ceases to fire repetitively.
