MAC15A10T

Triacs Overview

The MAC15A10T is a silicon bidirectional thyristor (Triac) from the MAC15 Series, designed for full-wave AC control applications. It features an 800 V peak repetitive off-state voltage and handles 15 A RMS on-state current in a TO-220AB package. The device utilizes diffused and glass-passivated junctions for stability and guarantees gate triggering in four modes. Key electrical parameters include a maximum holding current of 40 mA, a peak on-state voltage of 1.6 V at 21 A peak, and a thermal resistance junction-to-case of 2.0 °C/W.

Triacs Feature Summary

• Four-mode gate triggering capability for reliable switching
• Glass passivated junctions for enhanced parameter uniformity
• Thermowatt construction providing low thermal resistance

Triacs Applications

• Solid-state relays
• Motor controls
• Heating controls
• Power supplies

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the exact voltage rating and package configuration required for your design. Ensure compatibility with the TO-220AB mounting style and check lead soldering temperature limits during assembly. Confirm RoHS compliance status if material restrictions apply to your manufacturing process.

Triacs Selection Notes

Select this component when high blocking voltage up to 800 V is required alongside 15 A continuous current handling. Consider the four-mode sensitivity for flexible gate drive circuits. Evaluate thermal management requirements based on the specified junction-to-case thermal resistance and derating curves for your operating environment.

Triacs Part Context

This part belongs to the MAC15 Series of 15 Ampere Triacs manufactured by onsemi. The series includes variants with different voltage ratings such as 400 V, 600 V, and 800 V. All devices share similar physical dimensions and thermal characteristics while differing in their peak repetitive off-state voltage capabilities.

Triacs Replacement Considerations

Direct substitutes within the same series include MAC15A6G (400 V), MAC15A8G (600 V), and MAC15A10G (800 V). Cross-manufacturer replacements must match the 15 A RMS current, 800 V blocking voltage, and TO-220AB package footprint.
