BTA/BTB24, BT5, BT6 and T25 Series SNUBBERLESS & STANDARD 25A TRIACS MAIN FEATURES: Symbol Value Unit I T(RMS) 25 A V DRM /V RRM 6 and 8 V I T (Q1 ) 35 to 5 ma DESCRIPTION Available either in through-hole of surface and T25 mount packages, the BTA/BTB24-25-26 triac series is suitable for general purpose AC power switching. They can be used as an ON/OFF function in applications such as static relays, heating regulation, water heaters, induction motor starting circuits...or for phase control operation in high power motor speed controllers, soft start circuits...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 25V RMS) complying with UL standards (File ref.: E81734).
