| Do you know (or maybe remember) the Programmable Unijunction Transistor (PUT)? It was a special part in the '70s. In this article, we no...
| A thyristor can be turned on by applying a control signal to its gate, but it can only be turned off by interrupting the current flowing thr...
| There are situations that you might like to know if someone has been at your door (and rang the doorbell) during your absence. With, say, ni...
| We already ran into them a few weeks ago: thyristors and triacs – semiconductor switches for DC and AC respectively. As with many other semi...
| Inherent to their elementary design, thyristors and triacs acting as load switches are characterized by high cathode-anode voltage drop in t...
| The circuit in the diagram is a very handy tool for rapidly checking all kinds of thyristor (SCR, triac, …). In case of a triac, all fou...
