600 V, 3 A TRIAC for AC load switching
The Renesas Electronics AC03FSMA-AZ is a TRIAC rated at 600 V and 3 A, designed for switching AC loads in applications like motor speed controls, lighting dimmers, and heating controllers. With a 600 V blocking voltage, this part handles standard mains-line voltages (120 VAC, 230 VAC, 277 VAC) with margin for transients — a key parameter for reliability in industrial and appliance power stages.
Package and compliance detail
Supplied in Bulk packaging, the AC03FSMA-AZ is ROHS3 Compliant, meeting the latest EU restriction-of-hazardous-substances directive for lead-free assembly lines. The part belongs to the broad Discrete Semiconductors category, used in phase-control and AC power-switching circuits where a gate-drive signal triggers conduction in either direction.
