BTA12, BTB12, T12xx
12 A Snubberless™, logic level and standard triacs
Features
■ 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 ( 2002/95/EC) compliant
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.
