Skkt 250/16e, thyristor gate drive circuit

NANCHI · Feb 15, 2021

I want to drive two skkt 250/16e thyristors

Put 200mA into the gate and it will switch on.
It will switch off when anode current stops flowing.

The gate have two terminals, also need a v
Circuit to generate the 200mA.
Thanks

Because there are two thyristors.
12V supply, connected to gate through 47 ohm resistor
