For a 450 mA RMS load, the device latches reliably through each half-cycle. ## Active production, ROHS3 compliant, TO-92-3 package This TRIAC is listed as Active in ST's product status and ROHS3 compliant. The through-hole TO-92-3 package (formed leads) suits hand-assembly, prototyping, and retrofit on legacy boards. Tape & Reel (TR) and Cut Tape (CT) options are available for pick-and-place or small-quantity orders. ## Sourcing and BOM fit The ACS108-6SA-TR is a current-production, commercially available part sourced through independent distribution. It is quoted to order against an RFQ — availability and pricing are confirmed at quote time.","metaTitle":"ST ACS108-6SA-TR TRIAC, Sensitive Gate 600V 0.45A TO-92","metaDescription":"ACS108-6SA-TR TRIAC: 600V off-state, 450mA RMS, sensitive gate (10mA Igt).

Current availability and pricing are confirmed at quote time against an RFQ — no stock count or price is published here."},{"question":"Can ACS108-6SA-TR be used to control a 120 VAC load?","answer":"Yes. With 600 V off-state voltage and 450 mA RMS on-state current, it comfortably controls 120 VAC loads up to about 55 VA (resistive). The sensitive gate (10 mA Igt, 1 V Vgt) allows direct drive from 3.3 V or 5 V logic."},{"question":"What is the replacement for ACS108-6SA-TR?","answer":"There is no official successor from ST. The closest functional alternate in the same ACS family is the ACS108-8SN-TR (surface-mount, 800 V, 0.8 A) if you need higher voltage or an SMD footprint. For higher current, the ACST610-8T (through-hole, 6 A, 800 V) is a direct cross-shop candidate."},{"question":"Where to buy ACS108-6SA-TR?","answer":"ACS108-6SA-TR is available through independent semiconductor distributors.
