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