BTA/BTB12 and T12 Series ® SNUBBERLESS™, LOGIC LEVEL & STANDARD 12A TRIACS MAIN FEATURES: A2 Symbol Value Unit IT(RMS) 12 A G VDRM/VRRM A1 600 and 800 V A2 IGT (Q1) 5 to 50 mA DESCRIPTION A1 A2 Available either in through-hole or surface-mount G packages, the BTA/BTB12 and T12 triac series is suitable for general purpose AC switching. They D2PAK can be used as an ON/OFF function in (T12-G) applications such as static relays, heating regulation, induction motor starting circuits... or for A2 phase control operation in light dimmers, motor speed controllers,... The snubberless versions (BTA/BTB...W and T12 series) are specially recommended for use on inductive loads, thanks to their high commutation performances. Logic level versions are designed A1 A1 A2 A2
