SURGE CURRENT (A)
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.
