BTA12, BTB12, T1205 T1210, T1235, T1250 Datasheet 12 A Snubberless, logic level and standard Triacs A2 Features 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 G regulation or induction motor starting circuit. They are also recommended for phase A2 A1 control operations in light dimmers and appliance motors speed controllers. DPAK 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.
