Figure E2.13 Peak Surge Current versus Surge Current Duration
Figure E2.14 Normalized DC Holding Current versus Case Temperature
Figure E2.15 Turn-on Time versus Gate Trigger Current (Typical)
SUPPLY FREQUENCY: 60 Hz Sinusoidal
LOAD: Resistive
RMS ON-STATE CURRENT [l
]: Maximum
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.
