TXDVxx12 12 A high voltage Triacs Features A2 On-state current (I ): 12 A T(RMS) Max. blocking voltage (V /V ): 1200 V DRM RRM Gate current (I ): 100 mA G GT Commutation 10 V/s: up to 42.5 A/ms A1 Noise immunity: 2 kV/s Insulated package: 2,500 V rms (UL recognized: E81734). Description A1 A2 The TXDVxx12 series uses a high performance G alternistor technology. TO-220AB Featuring very high commutation levels and high insulated surge current capability, these devices are well adapted to power control for inductive and resistive loads (motor, transformer...) especially on three-phase power grid. Targeted three-phase applications include heating systems, motor starters, and induction motor speed control (especially for fans). Table 1.
