BTA24, BTB24, BTA25 BTA26, BTB26, T25
25 A standard and SnubberlessTM triacs
Features

High current triac Low thermal resistance with clip bonding High commutation (4 quadrant) or very high commutation (3 quadrant) capability BTA series UL1557 certified (File ref: 81734) Packages are RoHS (2002/95/EC) compliant

Applications
Applications include the ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits, etc., or for phase control operation in light dimmers, motor speed controllers, and silmilar. The snubberless versions (BTA/BTB...W and T25 series) are especially recommended for use on inductive loads, due to their high commutation performances. The BTA series provides an insulated tab (rated at 2500 VRMS).
