MAC15A6

Triacs Overview

The MAC15A6 is a silicon bidirectional thyristor (triac) from the MAC15 Series, designed for full-wave AC control applications. It features a peak repetitive off-state voltage of 400 V and an RMS on-state current rating of 15 A at a case temperature of +90°C. The device utilizes all diffused and glass passivated junctions to ensure parameter uniformity and stability. It operates within a junction temperature range of -40°C to +125°C and is housed in a rugged TO-220AB package with thermowatt construction for low thermal resistance.

Triacs Feature Summary

• Guaranteed gate triggering in four modes for reliable switching across all quadrants
• Diffused and glass passivated junctions for enhanced parameter stability
• Thermowatt construction providing low thermal resistance and high heat dissipation

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 compliance status. The base part number indicates the series, while suffixes such as 'G' denote lead-free packaging. Confirm RoHS compliance and assembly location codes directly with the manufacturer or authorized distributors before procurement.

Triacs Selection Notes

Select the MAC15A6 specifically when a 400 V blocking voltage is required, distinguishing it from higher voltage variants like the MAC15A8 (600 V). Ensure the application demands a 15 A RMS current capacity and can accommodate the TO-220AB through-hole package. Verify that the gate trigger requirements align with the specified maximum values for the selected operating quadrant.

Triacs Part Context

This component belongs to the MAC15 Series of silicon bidirectional thyristors manufactured by onsemi. The series covers a voltage range from 400 V to 800 V, with the MAC15A6 representing the 400 V variant. These devices are engineered for robust performance in general-purpose AC power control circuits requiring full-wave switching capabilities.

Triacs Replacement Considerations

MAC15A8G: Offers 600 V blocking voltage; verify if the lower 400 V rating of the MAC15A6 is sufficient for the circuit design.
