STMICROELECTRONICS ACS1207ST AC switch

The ACS120 is an overvoltage protected AC switch designed for reliable control of low power loads up to 2A in household appliances and HVAC systems. It features high blocking voltage of 700V, avalanche control with a typical voltage of 1100V, and high noise immunity, eliminating the need for external snubbers. Embedded with a high voltage clamp and gate level shifter, it ensures safe switching of inductive loads such as relays, fans, and defrost heaters. Its compact packages and direct microcontroller interface simplify installation and enhance system durability, meeting industry standards like IEC 61000-4-5 for surge immunity.
