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 V
RMS
).
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.
Table 1: Device summary
Features
