MAC228A8G

Triacs Overview

The Littelfuse MAC228A8G is a silicon bidirectional thyristor (TRIAC) designed for AC power control applications. It features a logic-sensitive gate configuration, allowing direct interfacing with microprocessor outputs without requiring high drive currents. The device is rated for a maximum repetitive off-state voltage of 600 V and an RMS on-state current of 8 A. Key electrical parameters include a maximum gate trigger current of 5 mA and a holding current of 15 mA. It operates within a junction temperature range of -40°C to 110°C and is housed in a TO-220AB through-hole package.

Triacs Feature Summary

• Logic-sensitive gate architecture enables direct connection to low-power digital logic circuits
• Glass-passivated junctions ensure long-term parameter stability and reliability
• High surge current capability supports robust performance during transient events

Triacs Applications

• Solid state relays and AC power switching modules
• Lighting control systems including dimmers and ballasts
• Motor speed controls and temperature modulation circuits

Triacs Procurement Notes

Verify the specific suffix 'TG' against the manufacturer's latest datasheet to confirm RoHS3 compliance and packaging details. Confirm availability status as distribution data may vary. Ensure the ordering quantity aligns with the manufacturer's standard pack size requirements before finalizing purchase orders.

Triacs Selection Notes

Select this component when a TRIAC requires direct interface with CMOS or TTL logic gates due to its low gate trigger current specification. The 600V rating makes it suitable for universal AC line applications. Verify that the thermal management design accommodates the TO-220AB package constraints for the expected RMS load current.

Triacs Part Context

This part belongs to the MAC228A series of silicon bidirectional thyristors from Littelfuse. The series offers various voltage ratings while maintaining consistent current handling capabilities. The MAC228A8G specifically denotes the 600V variant within this family, sharing common package and thermal characteristics with other members of the series.

Triacs Replacement Considerations

Direct substitutes include L6008R6TP and AVS12CB. Cross-reference gate trigger specifications carefully when substituting with devices like BTB08-600SWRG to ensure compatibility with existing logic drive circuits.
