SNUBBERLESS & STANDARD 25A TRIACS

MAIN FEATURES:
DESCRIPTION
Available either inthrough-hole of surfaceand T25
mount packages, the BTA/BTB24-25-26 triac
series is suitable for general purpose AC power
switching. They can be used as an ON/OFF
function in applications such as static relays,
heating regulation, water heaters,induction motor
starting circuits...or for phase control operation in
high power motor speed controllers, soft start
circuits...The snubberless versions (BTA/BTB...W
and T25 series) are specially recommended for
use on inductive loads, thanks to their high
commutation performances.
By using an internal ceramic pad, the BTA series
provides voltage insulated tab(rated at2500V
RMS) complying with UL standards (File ref.:
E81734).
