Two relatively recent technologies designed to reduce the “driving” (gate trigger current) requirements of classic...

If we take the equivalent circuit of an SCR and add another external terminal, connected to the base of the top...

Unijunction transistor: Although a unijunction transistor is not a thyristor, this device can trigger larger thyristors...

Like bipolar transistors, SCRs and TRIACs are also manufactured as light-sensitive devices, the action of impinging...

SCRs are unidirectional (one-way) current devices, making them useful for controlling DC only. If two SCRs are joined...

Shockley Diodes and Silicon Controlled Rectifiers (SCRs) Shockley diodes are curious devices, but rather limited in...

Like all diodes, Shockley diodes are unidirectional devices; that is, these only conduct current in one direction. If...

Our exploration of thyristors begins with a device called the four-layer diode, also known as a PNPN diode, or a...

If you’ve ever witnessed a lightning storm, you’ve seen electrical hysteresis in action (and probably didn’t...

Thyristors are a class of semiconductor components exhibiting hysteresis, that property whereby a system fails to...
