MAC3030-8G

Triacs Overview

The Littelfuse MAC3030-8G is a silicon bidirectional thyristor (triac) designed for AC power control applications. It features an 800V repetitive peak off-state voltage rating and a 15A average on-state current capability. The device utilizes a TO-220AB through-hole package with three pins, measuring 10.28mm in length, 4.82mm in width, and 15.75mm in height. Key electrical parameters include a maximum gate trigger current of 35mA, a maximum gate trigger voltage of 1.5V, and a peak on-state voltage of 1.6V. It supports a surge current rating of 150A and maintains operation within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Bidirectional switching capability for AC phase control
• Integrated diac structure for noise immunity
• Electrically isolated mounting tab

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the specific suffix '8G' against official Littelfuse documentation to confirm compliance with halogen-free and RoHS standards. Ensure the ordering part number matches the exact voltage and current ratings required for the target circuit design before procurement.

Triacs Selection Notes

Select this component for applications requiring integrated gate triggering without external discrete diacs. Verify that the load current does not exceed the 15A average rating and that the voltage spikes remain below the 800V blocking limit. Consider thermal management requirements given the TO-220AB package constraints.

Triacs Part Context

This device belongs to the Teccor Quadrac series by Littelfuse, which combines a triac and a diac trigger in a single package. This integration simplifies circuit design by eliminating the need for separate diac components and associated assembly steps, offering a cost-effective solution for AC switching.

Triacs Replacement Considerations

Direct replacements must match the 15A current, 800V voltage, and TO-220AB package. Verify pinout compatibility and gate trigger characteristics. Generic triacs lacking the integrated diac feature are not suitable substitutes for this specific Quadrac application.
