Thyristors are “normally-off” switches that can be triggered “on” by a small current pulse into the gate electrode. Once turned on (or “triggered”), the component then stays in the conducting state even when the gate on-signal is removed. It only returns to the “off” (blocking) state if the current falls below a certain minimum or if the direction of the current is reversed. Some sources define silicon controlled rectifiers and thyristors as synonymous. Our products portfolio includes some of the best brands i.e. , -Westcode, Epuec Proton-E, Semikron,  and various other National & International companies and provide our clients the opportunity to single source their requirements.
