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. |
