Maximum Working Voltages (V working)

The Maximum Working Voltage levels  can be derived from the appropriate formulae illustrated in the tables below. An example is shown at the foot of this page.

Waveforms are defined in the usual manner: 1.2 / 50 µs indicates a rise time to peak value in 1.2 µs and an exponential decay to half amplitude in a total time of 50 µs.
