MAC8SD, MAC8SM, MAC8SN
Preferred Device
Sensitive Gate Triacs
Silicon Bidirectional Thyristors
Designed 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 Allows Triggering by Microcontrollers and other
Logic Circuits
• Uniform Gate Trigger Currents in Three Quadrants; Q1, Q2, and Q3
• High Immunity to dv/dt — 25 V/ms Minimum at 110_C
• High Commutating di/dt — 8.0 A/ms Minimum at 110_C
• Minimum and Maximum Values of IGT, VGT and IH Specified for
Ease of Design
• On-State Current Rating of 8 Amperes RMS at 70_C
• High Surge Current Capability — 70 Amperes
• Blocking Voltage to 800 Volts
• Rugged, Economical TO220AB Package
• Device Marking: Logo, Device Type, e.g., MAC8SM, Date Code
