ON Semiconductor MAC228A8TG Triac

The MAC228A8TG is a high-performance triac developed by ON Semiconductor, designed to cater to a wide array of AC power control applications. This device is part of the MAC series, renowned for its reliability and efficiency in managing current flow in both directions. The MAC228A8TG is particularly suitable for use in motor control, lighting dimmers, and heating regulation systems, where precise and efficient control of AC power is essential.

With a maximum repetitive peak off-state voltage (Vdrm) of 800V, the MAC228A8TG is well-suited for applications operating at higher voltages. This feature ensures that the device can handle spikes and surges in the line voltage without compromising its performance or longevity. Additionally, the triac has a maximum on-state current (It(rms)) of 8A, making it capable of controlling moderate to high power loads with ease.

The triac's gate trigger current (Igt) is designed to be sensitive, allowing for the device to be triggered with a relatively low current, thus ensuring compatibility with a wide range of control circuits and microcontrollers. This sensitivity provides designers with greater flexibility when integrating the MAC228A8TG into their systems. Moreover, the device offers a non-repetitive peak on-state current (Itsm) of 80A, which is beneficial for applications that may experience short-term overload conditions.

The MAC228A8TG comes in a TO-220 package, a common and convenient package type that simplifies the mounting process on a PCB and offers good thermal performance. This makes it easier for designers and engineers to incorporate the triac into their designs without worrying about complex mounting procedures or heat dissipation issues.

ON Semiconductor has ensured that the MAC228A8TG meets stringent quality and performance standards. The device is characterized by its high noise immunity and minimal gate trigger current variation over the full operating temperature range, which enhances its reliability in a broad range of environmental conditions. Users can expect consistent performance and a long operational life, making the MAC228A8TG a smart choice for those in need of a robust AC power control solution.
