WebbIn this way both transistors feedback each other and the collector current of each goes on multiplying. This process is very quick and soon both the transistors drive each other to saturation. Now the device is said to be in.on-state. The current through the on-state SCR is controlled by external impedance only. Webb9 juni 2024 · Does a SCR ie Thyristor work for Inrush current protection in a circuit ? Yes it does. To limit inrush you need two things 1) something to limit current (higher resistance). 2) something to bypass the limiter (lower resistance). Now an NTC thermistor does satisfy these needs as its resistance starts off high and then decreases.

Unlike trying to make a transistor using two back-to-back diodes (which doesn't work at all because of the need to have a very thin base region separating the collector from the emitter), you can make an SCR using two discrete transistors, but it will behave quite differently in many respects from an integrated one. spvgg bayreuth fanforum
