Product details

What this part is and where it fits

The ST BTA08-800BWRG is an 800 V, 8 A RMS Snubberless Alternistor triac in a TO-220AB insulated full-pack package. 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.

Frequently asked questions

What is the equivalent of the BTA08-800BWRG?

The closest functional peer in the same Snubberless family is the BTA06-800BWRG, which is identical except for a 6 A RMS on-state current instead of 8 A. The BTB10-800BWRG is the 10 A version. All share the same 800 V off-state, TO-220AB package, and gate trigger characteristics.

Can the BTA08-800BWRG be used for AC switching?

Yes, it is designed for AC switching applications. The Snubberless Alternistor construction handles high dv/dt without external snubbers, making it suitable for resistive and inductive AC loads within its 8 A RMS and 800 V ratings.
