Sensitive Gate Triacs Silicon Bidirectional Thyristors

ON Semiconductor 

MAC12SM, MAC12SN

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

• Blocking Voltage to 800 Volts

• On-State Current Rating of 12 Amperes RMS at 70°C

• High Surge Current Capability - 90 Amperes

• Rugged, Economical TO220AB Package

• Glass Passivated Junctions for Reliability and Uniformity

• Maximum Values of IGT, VGT and IH Specified for Ease of Design

• High Commutating di/dt - 8.0 A/ms Minimum at 110°C

• Immunity to dV/dt - 15 V/msec Minimum at 110°C

• Operational in Three Quadrants: Q1, Q2, and Q3

• Device Marking: Logo, Device Type, e.g., MAC12SM, Date Code
