BTA12, BTB12, T12xx

12 A Snubberless™, logic level and standard triacs

Features

insulated BTA

commutation (3Q) capability

Applications

ON/OFF or phase angle function in applications

such as static relays, light dimmers and appliance

motors speed controllers.

The snubberless versions (BTA/BTB...W and T12

series) are especially recommended for use on

inductive loads, because of their high

commutation performances. The BTA series

provides an insulated tab (rated at 2500 V RMS).

Description

Available either in through-hole or surface-mount

packages, the BTA12, BTB12 and T12xx triac

series is suitable for general purpose mains

power AC switching.
