Thyristors Datasheet 2N6344 Surface Mount - 600-800V Pb Description The 2N6344 is designed primarily for full-wave AC control applications, such as light dimmers, motor controls, heating controls and power supplies; or wherever full-wave silicon gate controlled solid-state devices are needed. Triac type thyristors switch from a blocking to a conducting state for either polarity of applied anode voltage with positive or negative gate triggering. Features Blocking Voltage to 800 V All Diffused and Glass Passivated Junctions for Greater Parameter Uniformity and Stability Additional Information Resources Accessories Small, Rugged, Thermowatt Construction for Low Thermal Resistance, High Heat Dissipation and Durability Samples Gate Triggering Guaranteed in all Four Quadrants For 400 Hz Operation, Consult Factory Pb-Free Package is Available Functional Diagram Pin Out CASE 221A STYLE 4 1 2 1 (c) 2021 Littelfuse, Inc.
