It is designed for AC switching applications where a standard triac would need external snubber networks — the Snubberless construction handles high dv/dt without one, simplifying the BOM and board layout. Typical uses include solid-state relays, motor speed controllers, lighting dimmers, and industrial heating controls. The TO-220 full-pack isolates the tab, so no extra insulating washer is needed when bolting to a heatsink. ## Package and mounting — TO-220AB insulated The TO-220-3 Full Pack (supplier device package TO-220AB Insulated) is a through-hole package with the tab fully isolated. No additional insulating pad or bushing is required when mounting to a grounded heatsink. The full-pack construction also improves thermal cycling reliability compared to a non-isolated TO-220 with a separate insulator. ## Lifecycle and sourcing reality This part is Active in ST's portfolio — no last-time-buy notice, no obsolescence risk. It is ROHS3 compliant. For production BOMs, it can be specified without lifecycle concern. We source it through independent distribution and quote to order against an RFQ; availability and current pricing are confirmed at quote time.","metaTitle":"ST BTA08-800BWRG Snubberless Triac, 800V 8A TO-220AB","metaDescription":"ST BTA08-800BWRG Snubberless Alternistor triac, 800V off-state, 8A RMS.
