查询MAC228A供应商

MAC228A Series

Preferred Device

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.

• 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

• Device Marking: Logo, Device T ype, e.g., MAC228A4, Date Code
