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 does not prevent
the device from continuing to function, and to provide ample protection.
