MAC8MG

Triacs Overview

The Littelfuse MAC8MG is a bidirectional triac designed for high-current power control applications. It features an 80 A non-repetitive on-state current rating and a 600 V rated repetitive peak off-state voltage. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220-3 through-hole package. Key electrical parameters include a maximum holding current of 40 mA, a gate trigger voltage of 1.5 V, and a gate trigger current of 35 mA. It exhibits a typical on-state voltage of 1.6 V and a maximum off-state leakage current of 10 uA under specified conditions.

Triacs Feature Summary

• High current handling capability suitable for demanding power switching loads
• Logic-sensitive gate interface allowing direct drive from low-power control circuits
• Robust thermal performance supporting operation in elevated temperature environments

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay implementations
• AC power regulation circuits

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Cross-reference the Littelfuse part number with distributor listings to validate authenticity and traceability. Ensure the procurement channel provides valid component history documentation.

Triacs Selection Notes

Select this component when high surge current capacity is required alongside standard logic-level gate sensitivity. Evaluate the thermal management requirements for the TO-220-3 package based on the specific duty cycle and ambient conditions. Compare the 600 V blocking voltage against the system's peak line voltage to ensure adequate safety margins. Consider the 40 mA holding current constraint for load characteristics.

Triacs Part Context
