ACST1235-7G AC Switches by STMicroelectronics

Overvoltage protected AC switch


The ACST12 series belongs to the ACS™/ACST power switch family built with A.S.D. ® (application specific discrete) technology. This high performance device is suited to home appliances or industrial systems and drives loads up to 12 A. This ACST12 switch embeds a Triac structure and a high voltage clamping device able to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standard. The ACST1210-7 needs a low gate current to be activated (I GT < 10 mA) and still provides a high electrical noise immunity complying with the IEC 61000-4-4 standard. The ACST1235-7 offers an extremely high static dV/dt immunity of 2 kV/μs minimum.
