The thyristor keeps conducting after you take the gate signal away; a BJT would turn off then. That is, a BJT is a switch and a thyristor is a latching switch. > A triac is two thyristors connected together. Right? I don't see the > practical use for such a device. Can you give me a hint? The last 2 letters of "triac".
