thyristor thyristor


SCRs serve as switching devices working either in half-wave bridge circuits or in pulse mode. STs SCRs have multiple surface-mount packages and through-holes since RMS current ratings go up to 50 A while voltage ratings also extend up to 1200 V. Their advantage lies in being easily driveable, because of their low gate current triggering. This makes them perfect for all devices with low power needs where it is essential that power consumption remains low.

Accordingly, standard SCRs are best for all-purpose switching applications, be it motor control, crowbar protection with regard to power supply and regulation of battery voltage.
