ACST12xx / ACST10xx Triac Switches

STMicroelectronics ACST12xx and ACST10xx triacs belong to the ACS™ / ACST power switch family built with application-specific discrete technology. ACST12xx and ACST10xx overvoltage protected AC switches are triacs with overvoltage crowbar technology. STMicroelectronics ACST12xx and ACST10xx triacs embed 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 and ACST1010-7 need a low gate current to be activated and still provides a high electrical noise immunity complying with the IEC 61000-4-4 standard. The ACST1235-7 and ACST1035-7 offer an extremely high static dV/dT immunity of 2 kV/µs minimum.
