25 A standard and Snubberless™ triacs
Features A2
■ High current triac ■ Low thermal resistance with clip bonding
G
■ High commutation (4 quadrant) or very high
A1 A2
commutation (3 quadrant) capability ■ BTA series UL1557 certified (File ref: 81734) ■ Packages are RoHS (2002/95/EC) compliant
A1A2 A1 G A2G Applications TO-220AB Insulated TO-220AB (BTA24) (BTB24)
Applications include the ON/OFF function in
A1
applications such as static relays, heating
G A2
regulation, induction motor starting circuits, etc., or for phase control operation in light dimmers, motor speed controllers, and silmilar.
A1 A2 G
The snubberless versions (BTA/BTB...W and T25
RD91 TOP3 Insulated
series) are especially recommended for use on
(BTA25) (BTA26)
inductive loads, due to their high commutation performances. The BTA series provides an A2 insulated tab (rated at 2500 V
A2
RMS).

BTA24, BTB24, BTA25, BTA26, D2PAK TOP3 (T25) BTB26
and
T25
triac series is suitable for general
