This Technical Publication aims to provide an interesting, descriptive and practical introduction to the golden rules that should be followed in the successful use of thyristors and triacs in power ...

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 four quadrants are tested, which is done with S3, while in case of ...

Power-control modules are circuits comprising devices such as silicon-controlled rectifiers, triacs, power transistors, and power rectifier diodes. These circuits can function as pulse-width ...

The new device, named STSID140-12, is housed in a leadless DFN package measuring 5.35mm by 3.45mm and standing just 1.2mm high. Despite its small footprint, the driver integrates an isolation ...

Over on YouTube [Lockdown Electronics] reviews an old bit of kit known as the Silicon Controlled Rectifier (SCR). Invented in the 1950s the SCR is a type of thyristor and they were popular back in the ...

Triacs are at the heart of dimming controls for LED lighting. Triacs used in dimmers have normally been characterised and specified for incandescent lamp loads, which have high current ratings for ...

Solid-state relays are much smaller than corresponding single-pole relays. They are also faster, dissipate less power, and withstand a larger number of operations. And unlike electromechanical relays, ...
