Triacs
Silicon Bidirectional Triode Thyristors
. . . designed primarily for industrial and consumer applications for full wave control of
ac loads such as appliance controls, heater controls, motor controls, and other power
switching applications.
Sensitive Gate Triggering in 3 Modes for AC Triggering on Sinking Current
Sources (MAC228 Series)
Four Mode Triggering for Drive Circuits that Source Current (MAC228A Series)
All Diffused and Glass-Passivated Junctions for Parameter Uniformity and
Stability
Small, Rugged, Thermowatt Construction for Low Thermal resistance and High
Heat Dissipation
Center Gate Geometry for Uniform Current Spreading
