MAC08MT1G

Triacs Overview

The Littelfuse MAC08MT1G is a surface-mount bidirectional triac in an SOT-223 package. It features a peak repetitive off-state voltage of 600V and an on-state RMS current rating of 0.8A at 80°C case temperature. The device supports a peak non-repetitive surge current of 8.0A and operates within a junction temperature range of -40°C to +110°C. Electrical characteristics include a maximum gate trigger current of 10mA, a holding current of 5.0mA, and a peak on-state voltage of 1.9V. Thermal resistance from junction to ambient is 156°C/W when mounted on the recommended PCB footprint.

Triacs Feature Summary

• Sensitive gate trigger capability for reliable operation across four quadrants
• Glass passivated surface construction for enhanced reliability and uniformity
• Lead-free packaging option available for environmental compliance

Triacs Applications

• Motor control systems
• Process control circuits
• Temperature modulation controls
• Light dimming applications
• Speed control mechanisms

Triacs Procurement Notes

Verify the specific ordering suffix 'G' confirms lead-free status as documented in the manufacturer's ordering information table. Confirm the SOT-223 tape and reel shipping quantity matches project requirements. Ensure the selected component variant aligns with the required blocking voltage specifications for the target circuit design.

Triacs Selection Notes

Select this component for low-current AC switching applications requiring surface mount assembly. Evaluate thermal derating curves based on the specific copper pad area and ambient temperature conditions. Verify that the 0.8A RMS current rating accommodates the load requirements while maintaining safe operating junction temperatures under continuous duty cycles.

Triacs Part Context

This part belongs to the MAC08BT1/MAC08MT1 series of thyristors designed for industrial and consumer applications. The series offers blocking voltages up to 600V in a compact surface mount package. It serves as a solid-state alternative for mechanical relays in space-constrained designs requiring high-volume manufacturing compatibility.

Triacs Replacement Considerations

MAC08BT1G shares the same SOT-223 package and electrical ratings but differs in blocking voltage (200V). Direct substitution requires verifying that the lower voltage rating meets the circuit's peak reverse voltage demands without compromising safety margins.
