2N6344A/D

2N6344A, 2N6348A,

2N6349A

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 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*

*For additional information on our Pb−Free strategy and soldering details, please
