MAC15A10G

Triacs Overview

The Littelfuse MAC15A10G is a three-terminal triac designed for high-voltage AC switching applications. It features an average on-state current rating of 15 A and supports a non-repetitive surge current of 150 A. The device offers a repetitive peak off-state voltage (VDRM) of 1000 V, ensuring robust blocking capability in demanding circuits. Key electrical parameters include a maximum holding current of 40 mA and a peak on-state voltage of 1.6 V. The gate trigger voltage is specified at 2.5 V with a maximum gate trigger current of 75 mA. It operates within a temperature range of -40 °C to +125 °C and utilizes a TO-220-3 through-hole package.

Triacs Feature Summary

• High voltage blocking capability suitable for industrial power control
• Robust thermal performance supporting operation up to 125 °C
• Standardized TO-220-3 package for efficient heat dissipation

Triacs Applications

• Industrial motor speed control systems
• Solid-state relays for high-voltage loads
• Power regulation in heating elements

Triacs Procurement Notes

Verify the specific suffix 'G' against manufacturer documentation to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact voltage rating required, as variations exist within the MAC15 series. Cross-reference datasheets for precise thermal resistance values during integration planning.

Triacs Selection Notes

Select this component when a 1000 V blocking voltage is mandatory for the application circuit. Compare gate sensitivity requirements against the 75 mA trigger current specification. Evaluate thermal management needs based on the 15 A continuous current rating and available heatsinking options for the TO-220-3 package.

Triacs Part Context

This part belongs to the Littelfuse MAC15 series of general-purpose triacs. It shares the same physical footprint and basic current handling characteristics with lower voltage variants like the MAC15A6G and MAC15A8G. The primary differentiator is the increased voltage rating provided by the '10' suffix, indicating 1000 V capability.

Triacs Replacement Considerations

Direct substitutes include other 1000 V, 15 A triacs in TO-220 packages from manufacturers such as STMicroelectronics or Vishay. Verify pinout compatibility and thermal characteristics before substitution.
