MAC228A8TG

Triacs Overview

The MAC228A8TG is a logic-sensitive gate TRIAC manufactured by Littelfuse Inc., designed for through-hole mounting in TO-220AB packages. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current capacity of 8 A. The device requires a maximum gate trigger current of 5 mA and a gate trigger voltage of 2 V, enabling direct interfacing with microprocessor outputs. Non-repetitive surge current capability reaches 80 A at 60 Hz. Operating junction temperatures range from -40°C to 110°C, ensuring reliability in industrial environments.

Triacs Feature Summary

• Logic-sensitive gate architecture allows direct drive from standard logic circuits without additional amplification.
• High thermal robustness supports continuous operation up to 110°C junction temperature.
• Robust surge handling capability protects against transient overcurrent events during startup or fault conditions.

Triacs Applications

• Solid-state relays requiring low-power control signals
• Lighting dimmer circuits for residential and commercial loads
• Motor speed control systems for small AC motors

Triacs Procurement Notes

Verify the complete part number including suffixes such as 'OS' or 'G' when sourcing, as these may indicate specific packaging or compliance variations. Confirm RoHS3 status and manufacturing origin details via the official datasheet before finalizing procurement specifications to ensure compatibility with assembly processes.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 8 A continuous current are required in a TO-220AB package. Ensure the driving circuit can supply at least 5 mA gate current. Consider thermal management requirements given the 110°C maximum junction temperature limit and the power dissipation characteristics inherent to TRIAC operation in switching applications.

Triacs Part Context

This device belongs to the MAC228A series of logic-level TRIACs from Littelfuse. The series offers various voltage and current ratings within the same package footprint, facilitating design flexibility. The MAC228A8TG specifically targets applications needing moderate power handling with simplified gate drive requirements compared to standard sensitivity devices.

Triacs Replacement Considerations

Direct substitutes include L6008R6TP. Cross-brand alternatives like AVS12CB, BTB08-600SWRG, and T1610H-6T offer similar electrical characteristics but require verification of pinout compatibility and exact parameter matching against the original design specifications.
