12 A Snubberless™, logic level and standard Triacs
• Medium current Triac
• Low thermal resistance with clip bonding
• Low thermal resistance insulation ceramic for insulated BTA
• High commutation (4Q) or very high commutation (3Q) capability
• BTA series UL1557 certified (file ref: 81734)
• Packages are RoHS (2011/65/EU) compliant
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
regulation or induction motor starting circuit. They are also recommended for phase
control operations in light dimmers and appliance motors speed controllers.
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 VRMS) complying with UL standards (file reference: E81734).
Logic Level BTA12-600TW and BTA12-600SW offer low holding current, ideal to
design light dimmers for LED lamps.
