Preferred Device
Triacs
Silicon Bidirectional Thyristors
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 main terminal voltage with positive
or negative gate triggering.
• Blocking Voltage to 800 Volts
• All Diffused and Glass Passivated Junctions for Greater Parameter
Uniformity and Stability
• Small, Rugged, Thermowatt Construction for Low Thermal
Resistance, High Heat Dissipation and Durability
• Gate Triggering Guaranteed in all Four Quadrants
• For 400 Hz Operation, Consult Factory
• Device Marking: Logo, Device Type, e.g., 2N6344, Date Code

(1) VDRM and VRRM for all types can be applied on a continuous basis. Blocking
voltages shall not be tested with a constant current source such that the
voltage ratings of the devices are exceeded.
