SEMICONDUCTOR TECHNICAL DATA
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
