Overview
The ACST610-8GTR is a high-performance AC switch from STMicroelectronics, belonging to the ACS/ACST power switch family built with Application Specific Discrete (A.S.D.) technology. This device is designed for use in home appliances and industrial systems, capable of driving loads up to 6 A. It features a Triac structure with integrated overvoltage protection, enabling it to absorb inductive turn-off energy and withstand line transients as specified in the IEC 61000-4-5 standards. The ACST610-8GTR requires a low gate current for activation (IGT < 10 mA) and exhibits high noise immunity in compliance with IEC 61000-4-4 standards.
