Automatic voltage switches consist of a dedicated driver associated with a Triac for bi-voltage 120/240 V applications. The controller’s main features are full 50/60 Hz compatibility, the triggering pulse train of the Triac, the parasitic filter and low power consumption. Triac devices have a maximum voltage specified at 600 V and a maximum current up to 12 A.
They are available in DIP 8 packages for the driver and TO-220, TO-220I packages for the Triacs.
ST’s 8H Triacs have been designed for Industrial, Building, Residential, Appliances. Based on the new ST’s technology, the 8H Triacs are able to work at 800V & 150°C without compromise. It makes 8H Triacs the right choice to run in very hot confined electronic environment and improve the reliability of your system. Thanks to 8H Triacs robust dynamic turn-off commutation and high noise immunity at high temperature you can reduce your system size while increasing functional safety.
