POWER LOSSES (For 10 s, see note 1)
To evaluate the power losses, please use the following equations :
For the thyristor : P = 1.18 x I
For the diode : P = 0.67 x I

ambient temperature of 120 C in repetitive surge.
The curve of peak current versus the pulse
duration allows us to verify if the application is
within the FLC operating limit.
