SUPPLY FREQUENCY: 60 Hz Sinusoidal
LOAD: Resistive
RMS ON-STATE CURRENT: [IT(RMS)]: Max-
Rated Value at Specified Case Temperature
Notes:
1) Gate control may be lost during and
immediately following surge current
interval.
2) Overload may not be repeated until
junction temperature has returned to
steady-state rated value.
