WebFeb 12, 2024 · SCRs are like transistors but have the ability to latch, i.e. stay on once triggered, even if the gate signal is removed. They stay in conduction till the anode-cathode current drops below a certain value called the holding current. SCRs in many ways behave like diodes with similar forward drops, hence the name ‘controlled rectifier’.
