Triggered Spark Gaps
Ceramic-Metal
P
erkinElmer's Triggered
Spark Gaps are a family of versatile
high voltage switches. They consist
of three electrodes in a hermetically
sealed, pressurized ceramic enve-
lope. Triggered Spark Gaps are
generally characterized by a peak
current capability of thousands to
tens of thousands of amperes, delay
times of tens of nanoseconds, arc
resistance of tens of milliohms and
inductance of 5 to 30 nanohenries.
They are suitable for capacitor
switching applications such as flash-
lamps, electrically pumped gas
lasers, medical lithotripters, and
as crowbar protection devices.
Features
Fast switching operation
High voltage holdoff
Ceramic-metal construction
No warm up period

1.
Optimum operating voltage is typically 60 to 80% of SBV.
2.
Operation below minimum value may result in erratic firing
over time.
3.
Operation at this value may result in self-firing over time.
4.
Represents minimum main-gap breakdown voltage with no
trigger applied.
5.
Value shown contains safety factor for end-of-life requirements.
6.
PerkinElmer TM-11A Trigger Module can be used to trigger
all gaps.
7.
Transformers listed vary mechanically and electrically. See
PerkinElmer Transformer Data Sheet.
8.
These units must be operated in a liquid or gas dielectric to prevent
external flashover: GP-70 and GP-14B, above 24 kV; GP-32B and
GP-15B, above 35 kV; GP-74B and GP-81B, above 60 kV.
9.
Designed for high altitude, high holdoff conditions.
10. Other voltage ranges and mechanical configurations are available
on request; for example, the GP-20B can be supplied with a 6 to
16 kV operating range by specifying GP-20B-20. The 20 would be
the SBV and E-E maximum would be 80% of SBV = 16kV.
11. E = Stored energy in joules (1/2CV
2
), lb = average current in
amperes, lp = RMS current in amperes, R = total circuit resistance
in ohms, P = average power in watts.
