PEAK CURRENT LIMIT
This compo nen t is des ig ne d to wit h st and
Ip = 150A for a pulse duration of 10 s for an ambi-
ent temperature of 90 C.

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
2/ BLANKING MODE (Transistor T
In this mode and transistor T is saturated and stops
the spark generation.

The curve of peak current versus the pulse dura-
tion allows us to verify if the application is within the
FLC operating limit.
In order to keep the thyristor Th in blanking mode
and because of the power dissipation, the Resistor
(Rs) has to keep a minimum value of 22 k
