MAC15SNG

Triacs Overview

The MAC15SNG is a bidirectional triac manufactured by Littelfuse, belonging to the MAC12SN series. It features an RMS on-state current of 12 A and a non-repetitive peak on-state current of 90 A. The device supports a rated repetitive off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 10 uA at VDRM. Key electrical parameters include an on-state voltage of 1.85 V, a maximum holding current of 10 mA, a gate trigger voltage of 1.5 V, and a gate trigger current of 5 mA. It operates within a temperature range of -40 C to +110 C and is housed in a TO-220-3 through-hole package.

Triacs Feature Summary

• Bidirectional switching capability for AC power control applications
• High surge current handling with 90 A non-repetitive peak rating
• Integrated thermal management via TO-220-3 leaded package

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the manufacturer designation carefully, as the MAC15SNG part number is associated with Littelfuse rather than onsemi. Confirm the specific datasheet version and RoHS compliance status directly from the supplier before procurement. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel quantities, to align with assembly requirements.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 12 A continuous current capacity are required for AC load switching. The TO-220-3 package facilitates heatsinking for high-power dissipation scenarios. Verify that the gate trigger characteristics meet the driving circuit capabilities, particularly the 5 mA trigger current requirement for reliable turn-on.

Triacs Part Context

The MAC15SNG belongs to the MAC12SN series of triacs produced by Littelfuse. This series is designed for general-purpose AC power control applications requiring robust performance and reliability. The component utilizes silicon planar technology to ensure stable operation across the specified industrial temperature range.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers for the MAC15SNG were not identified in the provided documentation. Cross-reference with other 12 A, 800 V triacs in TO-220 packages only after verifying pinout compatibility and electrical parameter equivalence.
