BTA12, BTB12, T12xx
12 A Snubberless™, logic level and standard Triacs
Datasheet - production data
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 performance. The BTA series
provide an insulated tab (rated at 2500 VRMS).
Description
Available either in through-hole or surface mount
packages, the BTA12, BTB12 and T12xx Triac
series are suitable for general purpose mains
power AC switching.
