T8H High temperature 8 A sensitive TRIACs Features Medium current TRIAC Logic level sensitive TRIAC 5 C max. T j turn-off commutation G Clip bounding A RoHS (22/95/EC) compliant packages Applications The T8H is designed for the control of AC actuators in appliances and industrial systems. The multi-port drive of the microcontroller can control the multiple loads of such appliances and systems through these sensitive gate TRIACs. A G D 2 PAK T8H-6G A TO-22AB T8H-6T G Description Specifically designed to operate at 5 C, the new 8 A T8H TRIACs provide an enhanced performance in terms of power loss and thermal dissipation. This allows the optimization of the heatsink size, leading to space and cost effectiveness when compared to electromechanical solutions. Based on ST logic level technology, they offer an I GT lower than ma and specified minimal commutation and high noise immunity levels valid up to the T j max. Table.
