NOTE: If pulse ratings are exceeded, a shift of VN(DC) (at specified current)
of more than ±10% could result. This type of shift, which normally results in a
decrease of VN(DC), may result in the device not meeting the original pub-
lished specifications, but it does not prevent the device from continuing to
function, and to provide ample protection.
