Allow me to refresh you with the basics. The SCR has three terminals: cathode, anode and gate. The device can be turned on by a trigger voltage at the gate. Once there is current from anode to cathode ...

Recent studies have introduced innovative approaches such as double snapback SCR designs that demonstrate enhanced ESD triggering mechanisms and reduced device footprint, thereby catering to ...

A trigger pulse is issued to the SCR gate when V C3 = V C2. This, in turn, generates the V C2 /SCR phase-conversion function and also resets C3 via Q5.
