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 published specifications, but it does not prevent the device from continuing to function, and to provide transient protection
