I need to switch 4 x 650W heating elements, each with a one BTA208S-800E triac. While other power electronic switches like MOSFET, ... two equivalent SCRs in inverse parallel to one another and the gates of the two SCR are connected together to form a single gate. With switch SW1 open, no current flows into the Gate of the triac and the lamp is therefore “OFF”. The DIAC (diode for alternating current) is a diode that conducts electrical current only after its breakover voltage, V BO, has been reached momentarily. It is least when the triac is triggered close to 00 and 1800 zero crossing points but maximum in 90 0 wave form. If the switch is thrown into position 2, a small gate current flows through the gate terminal and hence the triac is turned ON. Also, in using this very basic form of control, the current flow through the SCR is only controllable over half of the positive half cycle, that is a quarter of the full AC cycle. The Thyristor is held in the off condition -- that is, all current flow in the circuit is blocked by the Thyristor except a minute leakage current. Full forms related VLSI.
