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 ...

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 ...

Programmable Unijunction Transistor Gate Drivers Both the main and commutation SCRs have their gates driven by PUT (Programmable Unijunction Transistor) circuits. Advantages are high gate drive ...

Because all of these factors are reasonably constant at a given temperature, the sink current also stays the same even though V S may vary considerably. In tests on a prototype circuit with R3 = 2 ...

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.
