Thyristor starter for fluorescent tubes

The Type Y112 fluoractor(TM) fromTexas Instruments is a specially designed thyristor for starting fluorescent tubes. Its main advantages over a standard thyristor are its much greater hold current. Its ability to cope with rapidly rising anode-cathode voltages (high du/dt value), and its overvoltage proteetion. These properties make it very suitable for replacing a traditional electro-mechanical starter for reliable flicker-free starting and a long life.
