The Silicon-Controlled Rectifier (SCR)
The necessary gate current to initiate latch-up, of course, will be much lower than
the current through the SCR from cathode to anode, so the SCR does achieve a
measure of amplification. This method of ... But even with a GTO, the gate current
required to turn it off may be as much as 20% of the anode (load) current!
