Overview
The ACST610-8R is a high-performance AC switch from STMicroelectronics, part of 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 along with a high voltage clamping device, which absorbs inductive turn-off energy and withstands line transients as specified in IEC 61000-4-5 standards. The ACST610-8R requires a low gate current (IGT < 10 mA) for activation and exhibits high noise immunity, complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).
