Despite being marked as obsolete, the MAC97A6G remains popular among engineers for its robust performance and cost-effectiveness. In this comprehensive guide, we ll explore its specifications, features, and practical applications to help you determine if it s the right choice for your project.

Detailed Specifications of MAC97A6G

1. Triac Type: Logic-Sensitive Gate

The MAC97A6G is a logic-sensitive gate TRIAC, meaning it can be triggered with low gate currents (as low as 5mA). This makes it compatible with microcontroller outputs and digital logic circuits, eliminating the need for additional drivers.

2. Voltage Rating: 400V (Vdrm/Vrrm)

With a 400V off-state repetitive peak voltage, the MAC97A6G is suitable for standard AC mains applications (e.g., 110V/220V systems). This ensures safe operation in household and industrial environments.

3. Current Handling: 600mA RMS

The TRIAC supports up to 600mA RMS continuous current, making it ideal for controlling small loads like LEDs, relays, and low-power motors. Its surge current capability (8A at 60Hz) adds durability against transient spikes.

4. Gate Trigger Voltage: 2V Max

The low 2V gate trigger voltage simplifies interfacing with 3.3V/5V logic circuits, reducing design complexity and BOM costs.

5. Thermal Performance: -40 C to 110 C

Rated for a wide temperature range (-40 C to 110 C), the MAC97A6G performs reliably in harsh conditions, from industrial machinery to outdoor lighting systems.

6. Package: TO-226-3 (TO-92-3 Long Body)

The compact TO-92 through-hole package ensures easy PCB mounting and efficient heat dissipation, even in space-constrained designs.
