operating voltage range is desired. The
low end of the operating voltage range
is independent of the Static Breakdown
Voltage (SBV). Operating ranges from
300 volts to 80 kilovolts are possible.
Switching times (from the trigger input
to the start of main gap current flow) of
less than 1 microsecond may be
achieved when using a suitable trigger.
These switches are commonly used in
“crowbar” circuits for protection against
overvoltage conditions.
Features
• Wide operating voltage range
• Ceramic-metal construction
• No warm up period
• High current capability
• Long life

The operating characteristics shown here are intended as an aid to preliminary gap selection. The characteristics listed are typical for the indicated
types under standard environmental conditions. The conditions found in
many applications will influence gap operating characteristics; therefore,
some characteristics may not be simultaneously achievable. Prospective
users of these gaps should be aware of the limitations in the data being presented. Contact PerkinElmer for information concerning the performance to
be expected in the intended application.
SBV is the Static (Self) Breakdown Voltage. It is the dc voltage across the
main gap (between the opposite and adjacent electrodes, O-A) above which
the gap is likely to break down (conduct) with no trigger applied.
The peak current applies for a critically damped discharge. Current reversals
degrade life, so gap operation in the underdamped condition should be
avoided when possible.
In underdamped circuits, each current half-cycle contributes to the total conducted charge, i.e., conducted charge increases independently of the direction of gap current. Therefore, the total conducted charge, including any “fol-

low-through” current, should not exceed the maximum conducted charge
indicated.
Includes an internal shield to slow deposits of discharge debris on the insulating ceramic.
A small amount of metallic mercury is used in these gaps to aid in the formation of the initial discharge. These gaps should not be operated above 50°C.
Care should be exercised in the handling and disposal of these gaps.
Proper application of these gaps may require them to be immersed in insulating oil or gas depending on the operating voltage level and environmental
factors. A method to circumvent electrical breakdown across the outside surfaces of the ceramic insulators of the gap may be necessitated in some
uses. Some of the more important factors to consider in determining the
insulation qualities of the environment are altitude (local atmospheric
pressure); humidity; dust; cleanliness; temperature and pulsed versus
dc operation.
