BTA24, BTB24, BTA25, BTA26 and T25 series Snuberrless™ and Standard 25 A Triacs Main features TO-220AB (BTB24) TO-220AB Insulated (BTA24) Symbol Value Unit IT(RMS) 25 A VDRM/VRRM 600 and 800 V IGT (Q1) 35 to 50 mA Description Available either in through-hole or surface-mount packages, the BTA24, BTB24, BTA25, BTA26 and T25 triac series is suitable for general purpose AC switching. They can be used as an ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits... or for phase control operation in light dimmers, motor speed controllers, ... RD91 (BTA25) TOP3 Insulated (BTA26) The snubberless versions (BTA/BTB...W and T25 series) are specially recommended for use on inductive loads, thanks to their high commutation performances. By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500VRMS) complying with UL standards (File ref.: E81734).
