MAC228A6G

Triacs Overview

The MAC228A6G is a bidirectional triac from the Littelfuse MAC228A6 series, designed for sensitive gate triggering applications. It features an 80 A non-repetitive peak on-state current and a rated repetitive off-state voltage (VDRM) of 400 V. The device exhibits a maximum holding current of 15 mA, with a typical on-state voltage of 1.8 V. Gate triggering requirements include a maximum voltage of 2.5 V and a maximum current of 10 mA. Operating within a temperature range of -40°C to +110°C, it utilizes a TO-220-3 through-hole package.

Triacs Feature Summary

• Sensitive gate architecture enabling reliable triggering with low gate drive currents
• High surge current capability suitable for demanding AC power switching loads
• Integrated thermal management via metal tab in TO-220-3 package

Triacs Applications

• AC motor speed control circuits
• Solid-state relay implementations
• Lighting dimmer applications

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number and date code against official Littelfuse documentation. Confirm that the TO-220-3 package marking matches the specific MAC228A6G designation to avoid substitution errors during assembly.

Triacs Selection Notes

Select this component when a high-current bidirectional switch is required with sensitive gate drive compatibility. Ensure the circuit design accommodates the 400 V blocking voltage and that the thermal solution supports the 80 A surge rating under expected load conditions.

Triacs Part Context

This device belongs to the MAC228A6 family of thyristors manufactured by Littelfuse. It serves as a robust AC power control element within the broader portfolio of power semiconductors and solid-state switches offered by the company for industrial and consumer electronics markets.

Triacs Replacement Considerations

The part number alias MAC228A6TG indicates a potential equivalent variant. Verify pinout compatibility and electrical parameter equivalence before substituting.
