WebIt is a semi-controlled switch that can be switched on by applying a positive gate current but it lacks the ability to be turned off using the same gate. The main current must be interrupted to turn off the thyristor using a commutation circuit. … Web22 May 2024 · The BJT acts as a switch, completing the circuit between the DC supply, the LED and the current limiting resistor, R C. For this to work reliably, we have to make sure that the ratio of saturation current to base current is much less than β. A value of 10 or so would guarantee hard saturation.
