BTA12, BTB12, T1205 T1210, T1235, T1250 Datasheet 12 A Snubberless™, logic level and standard Triacs Features A2 • Medium current Triac • Low thermal resistance with clip bonding G • Low thermal resistance insulation ceramic for insulated BTA A1 • High commutation (4Q) or very high commutation (3Q) capability A2 • BTA series UL1557 certified (file ref: 81734) • Packages are RoHS (2011/65/EU) compliant G G A2 A2 A1 A1 Description TO-220AB TO-220AB Ins. A2 Available either in through-hole or surface mount packages, the BTA12, BTB12 and T12xx Triac series are suitable for general purpose mains power AC switching. They can be used as ON/OFF function in applications such as static relays, heating A2 G regulation or induction motor starting circuit. They are also recommended for phase A1 control operations in light dimmers and appliance motors speed controllers. D²PAK The Snubberless™ versions (W suffix and T12xx) are especially recommended for use on inductive loads, because of their high commutation performance. By using an internal ceramic pad, the Snubberless™ series provide an insulated tab (rated at 2500 V ) complying with UL standards (file reference: E81734). RMS Logic Level BTA12-600TW and BTA12-600SW offer low holding current, ideal to design light dimmers for LED lamps.
