Notes:
 Calculated continuous current based on maximum allowable junction
temperature. Bond wire current limit is 90A. Note that current
limitations arising from heating of the device leads may occur with
some lead mounting arrangements. (Refer to AN-1140)
 Repetitive rating; pulse width limited by max. junction temperature.
