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),
TO-220AB Insulated
(BTA12)
TO-220AB
(BTB12)
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.
