MAC228A/D
MAC228A Series
Sensitive Gate Triacs
Silicon Bidirectional 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.
Features
• Sensitive Gate Triggering in 3 Modes for AC Triggering on
Sinking Current Sources
• Four Mode Triggering for Drive Circuits that Source Current
• 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
• These Devices are Pb−Free and are RoHS Compliant*
*For additional information on our Pb−Free strategy and soldering details, please
