Webb6 juli 2024 · This circuit works similarly to an SCR. When the trigger input is high, Both transistors Q2 (PNP transistors) and Q1 (PNP transistors) will work. Therefore, the current flows to the base pin of Q2, which has a voltage of 0.7 volts at resistor R1. When we cut the trigger voltage, the transistors can continue to work, because of the base current.
