I'm not using it to switch AC, but DC. As a bidirectional device, a triac should be able to swing both ways, yes?Yes , but you have to change the gate signal too, as long as the Gate is the same polarity as MT2, .
There are 4 Triac Quadrants for triggering.
That's fine, I'm discharging a capacitor bank. I'm new to both devices... can we switch an SCR with a diac?Hello,
When a triac or thyristor is fired, it needs the voltage to go to almost zero to reset.
The triac or thyristor will "reset" below the holding current.
