Fig. 3: Relative variation of thermal impedance
versus pulse duration.
Fig. 4: On-state characteristics (maximum
values).
Fig. 5: Surge peak on-state current versus
number of cycles.
Fig. 6: Non-repetitive surge peak on-state
current for a sinusoidal pulse with width
tp < 10 ms, and corresponding value of I t.
Fig. 7: Relative variation of gate trigger current,
holding current and latching current versus
junction temperature (typical values).
Fig. 8: Relative variation ofcritical rate of decrease
of main currentversus (dV/dt)c (typical values).
