Description

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.
