T = Time from 10% to 90% of Peak
T 1 = Rise Time = 1.25 x T
T 2 = Decay Time
Example:
For an 8/20 μ s Current Waveform:
8 μ s = T 1 = Rise Time
20 μ s = T 2 = Decay Time

NOTE: If pulse ratings are exceeded, a shift of V N(DC) (at speci?ed current) of more than +/-10% could result. This type of shift, which normally results in a decrease of V N(DC) , may result in
the device not meeting the original published speci?cations, but it does not prevent the device from continuing to function, and to provide ample protection.
