NOTE: If pulse ratings are exceeded, a shift of V
N(DC)
(at specified 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 specifications, but it does not prevent the device from continuing
to function, and to provide ample protection.
