* ICL is measured 1ms after the maximum peak
** Pulsed: Pulse duration = 300 µs, duty cycle 1.5 %
Note 1: After adjusting input signal (frequency and duty) to be IC = 5A, Vin (Tr ON) should be measured.
Note 2: The device is biased with 14V on collector with respectto emitter. Then a voltage ramp (0 to 5V) is put on input. VinTH is the input
voltage when the device is in on-state with IC=5A
