WebChapter 9: Thyristors Thyristors Thyristors are a class of semiconductor devices characterized by 4-layers of alternating p- and n-material. Four-layer devices act as either open or closed switches; for this ... This is the value of anode current below which the SCR switches from the forward-conduction region to the forward-blocking region. WebAug 3, 2024 · When the ON button is pressed a small current will flow into the gate. We can calculate the current using Ohm's law. I = V R = 9 1000 = 9 m A. This will be safe for the thyristor. The thyristor will turn on and the LAMP1 will light. If you let go the ON button the LAMP1 will stay on. This is how thyristors work.
