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. ## 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. 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.","metaTitle":"ST BTA08-800BWRG Snubberless Triac, 800V 8A TO-220AB","metaDescription":"ST BTA08-800BWRG Snubberless Alternistor triac, 800V off-state, 8A RMS.
