The ACST12 is a high performance power switch from STMicroelectronics, suitable for home appliances or industrial systems and drives loads up to 12A. This 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 (IGT < 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.
The ACST12 series belongs to the ACS power switch family built with A.S.D. technology. This high-performance device is suited for home appliances or industrial systems and drives loads up to 12 A. The switch embeds a Triac structure and a high voltage clamping device able to absorb inductive turn-off energy and withstand line transients described in the IEC 61000-4-5 standard.
