DESCRIPTION
Available either in through-hole of surface and 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 at 2500V
RMS) complying with UL standards (File ref.:
E81734).
