Notes

1. The DC voltage at which the gap switches from the open to the con-

ducting state. (For any given gap, SBV has a single fixed value).

2. The SBV of an individual gap may be +/- 10% of its nominal value.

Therefore, the recommended maximum operating (standoff) voltage is

80% of SBV.

3. The range shown is typical for dv/dt between 75 and 300 kV/us.

4. The maximum dynamic breakdown voltage is 1000 volts for gaps

having SBV between 500 and 750 volts. For higher SBV, DBV is

approximately 1.3 times SBV.

5. Typical life at rated conducted charged is 500-1000 operations. Life

increases substantially at lower operating levels.
