MAC228A10G

Triacs Overview

The MAC228A10G is a sensitive gate triac manufactured by Littelfuse, designed for high-power AC switching applications. It features an 80 A non-repetitive peak on-state current and an 800 V rated repetitive off-state voltage (VDRM). The device operates within a junction temperature range of -40°C to +110°C and utilizes a TO-220-3 through-hole package. Key electrical characteristics include a maximum holding current of 15 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 10 mA. The component exhibits a low on-state voltage of 1.8 V and a maximum off-state leakage current of 10 µA at VDRM.

Triacs Feature Summary

• Sensitive gate architecture enabling direct interfacing with microprocessor drivers
• High surge current capability suitable for inductive load switching
• Robust thermal performance optimized for through-hole mounting

Triacs Applications

• Solid-state relays
• Industrial motor control circuits
• AC power regulation systems

Triacs Procurement Notes

Verify the specific Littelfuse datasheet revision to confirm compliance with RoHS and REACH standards prior to integration. Ensure that the TO-220-3 package dimensions align with the target PCB footprint and thermal management requirements. Cross-reference the part number alias MAC228A4G if sourcing from distributors utilizing alternate nomenclature.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 80 A surge capacity are required for sensitive gate triac applications. The 10 mA gate trigger current allows for efficient drive circuit design compared to standard gate devices. Consider the TO-220-3 package for applications requiring effective heat dissipation without complex mounting hardware.

Triacs Part Context

This device belongs to the MAC228A10 series of sensitive gate triacs. It shares functional similarities with other members of the family but is distinguished by its specific 800 V voltage rating. The 'G' suffix typically indicates environmental compliance or specific packaging variations within the manufacturer's catalog.

Triacs Replacement Considerations

The MAC228A6G serves as a related alternative within the same product family, offering identical current ratings but with a reduced 400 V voltage rating. Verify voltage requirements before substituting.
