2N6344A_06 Datasheet, PDF (1/7 Pages) ON Semiconductor – Triacs Silicon Bidirectional Thyristors

2N6344A, 2N6348A,
2N6349A
Triacs
Preferred Device
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 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
• 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
• 8.0 A Devices Available as 2N6344 thru 2N6349
• Pb−Free Packages are Available*
