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
NOTES:
1. Tab is designed to fit 1/4” quick-connect terminal.
2. Case temperature is measured at T

on top surface of base
plate.
