ACS are static-switch semiconductors for alternating current. They are simple-to-drive, sensitive-gate devices with highly inductive load switch-off capability. They are targeted at appliance actuators, such as water valves and drain pumps.
Their logic-level gate characteristics allow direct input from the microcontroller. The high immunity of the device reduces the need for MOVs and snubbers in the circuit.
These devices have a 600 V blocking capability with further clamping and crowbar features for large overvoltage transients.
They are available in SO-8, SO-20, SOT-223 or TO-92 packages.
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.
