I understand that when \$TR_1\$ and \$TR_2\$ are ideal transistors, we need an initial \$I_G\$ current pulse signal in \$G\$ to turn on the thyristor. This \$I_G\$ will turn on \$TR_2\$ and the ...
I am building a small circuit to turn on/off a 200W heater. I am using a MOC3023 and a BT136. At the datasheet of the the optotriac, this circuit is recommended: My question is how is the 180Ohm ...
I'd like to create a simple circuit for keeping a line "high" for a few seconds after being triggered high, without any external power. To specify it in more detail: given three inputs, 3.3V, GND and ...
Well, I've recently started reading about thyristors and I have been stuck by something my instructor said about the turn-on process. During the forward-biased state of the thyristor the junctions ...
Similar to this question, I need a replacement for a programmable unijunction transistor [PUT]. Specifically, I'm trying to emulate the behavior described in the 2N6028 datasheet. However, I would ...
I recently ran into an interesting device called a thyratron. I have a basic understanding of thyratrons as gas filled vacuum tubes. I understand that they can switch large amounts of currents and ...
I know that kind of things could be done by thyratrons, but wikipedia says that they are being phased out by semiconductor devices. Could anyone suggest which kind of devices can switch on that fast ...
As part of my 2330 lv3 am required to know about thyristors. I just want to confirm my understanding is correct. A thyristor is basically similar to a transistor, only it stays switched on when it's ...
