Table 1: Main Features

DESCRIPTION
Available either in through-hole or surface-mount
packages, the BTA06 and BTB06 triac series is
suitable for general purpose AC switching. They
can be used as an ON/OFF function in applica-
tions such as static relays, heating regulation, in-
duction motor starting circuits... or for phase
control operation in light dimmers, motor speed
controllers,...

The snubberless and logic level versions (BTA/
BTB...W) 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).
