Datasheet - production data
Description
Available either in through-hole or surface mount
packages, the BTA10, BTB10 and T10xx Triac
series are suitable for general purpose mains
power AC switching. They can be used as
ON/OFF function in applications such as static
relays, heating regulation or induction motor
starting circuit. They are also recommended for
phase control operations in light dimmers and
appliance motors speed controllers.
The Snubberless™ versions (W suffix and T10xx)
are especially recommended for use on inductive
loads, because of their high commutation
performance. By using an internal ceramic pad,
the Snubberless™ series provide an insulated
tab (rated at 2500 V
RMS
) complying with UL
standards (file reference: E81734).
