ON Semiconductor MAC12N Triac

The ON Semiconductor MAC12N is a high-performance triac designed for use in AC load control applications. This semiconductor device is capable of switching and controlling large AC power loads with high efficiency and reliability. The MAC12N is a member of the TRIAC (Triode for Alternating Current) family, which is a type of bidirectional thyristor. It is designed to switch on and off in both parts of an AC cycle, making it an ideal choice for phase control in light dimmers, motor speed controllers, and other similar applications.

Key Features

• High Blocking Voltage: The MAC12N boasts a high repetitive peak off-state voltage (VDRM) of 800V, which makes it suitable for applications requiring high voltage operation.
• Current Handling: With a continuous on-state current (IT(RMS)) of 12A, it can handle significant power levels, making it appropriate for a broad range of AC power applications.
• Gate Trigger Current: The device has a sensitive gate trigger current (IGT), which allows for direct interfacing with microcontroller outputs and other low-power gate trigger circuits.
• Surge Capability: The MAC12N can withstand surge currents up to 100A, providing robust performance during short-term overload conditions.
