The curve of peak current versus the pulse

duration allows us to verify if the application is

within the FLC operating limit.

POWER LOSSES (For 10µs, see note 1)

To evaluate the power losses, please use the following equations :

For the thyristor : P = 1.18 x IT(AV) + 0.035 I2T(RMS)

For the diode : P = 0.67 x IF(AV) + 0.106 I2F(RMS)
