Overview
The ACST210-8FP is a high-performance AC switch from STMicroelectronics, part of the ACS/ACST power switch family. This device is designed for use in home appliances and industrial systems, capable of driving loads up to 2 A. It features a Triac structure with overvoltage crowbar technology to absorb inductive turn-off energy and withstand line transients as specified in IEC 61000-4-5 standards. The component requires a low gate current (IGT < 10 mA) and exhibits high electrical noise immunity, complying with IEC standards such as IEC 61000-4-4 for fast transient burst tests.
