STMICROELECTRONICS ACS1207SB AC Switch

The ACS120 is an overvoltage protected AC switch designed for low power switching applications such as appliance control systems, relays, valves, and motors. It features high noise immunity, avalanche control, and does not require external snubbers, simplifying design and reducing component count by up to 80%. Suitable for switching inductive loads up to 2A, the device employs a high voltage clamping structure to absorb inductive energy and ensures safe operation during surge conditions and overvoltage events, making it ideal for reliable and efficient AC line switching.
