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 ...

Crydom has added two new series of high-current silicon controlled rectifiers (SCRs) and three series of high-current triac/alternistors. The SCRs will be available with 40-A and 55-A ratings in a ...

Silicon-controlled rectifiers (SCRs) are interesting devices that can be used for on-chip ESD protection, if (and only if) they are properly designed and biased. SCRs ...

Modern power control systems utilize electronic devices like Thyristors for power switching, phase control, chopper etc. These devices also find applications in inverter design, brilliance control in ...

The R820 Series silicon control rectifiers provide modulation of electric loads using industry-standard proportional controls from thermostats and building systems. It incorporates a compact control ...

Fig 1. This efficient pre-regulator for a dc power supply uses an optical feedback loop to minimize dissipation rather than the traditional optically isolated TRIAC drivers. Fig 2. The PSpice ...

Although the silicon controlled rectifier or SCR has been around since 1957, it doesn’t get nearly the love an ordinary transistor does. That’s a shame because they are quite handy when it comes to ...
