T1205 pdf
BTA12, BTB12, T12xx
12 A Snubberless™, logic level and standard Triacs
Datasheet - production data
Features
Medium current Triac
Low thermal resistance with clip bonding
Low thermal resistance insulation ceramic
for insulated BTA
High commutation (4Q) or very high
commutation (3Q) capability
BTA series UL1557 certified (file ref: 81734)
Packages are RoHS (2002/95/EC) compliant
Applications
ON/OFF or phase angle function in applications
such as static relays, light dimmers and
appliance motors speed controllers.
The Snubberlessversions (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.
