MAC15SMG

Triacs Overview

The MAC15SMG is a silicon-controlled rectifier (SCR) manufactured by onsemi, designed for high-power switching applications. It features a standard TO-220AB insulated package with a single terminal mount. The device supports a repetitive peak reverse voltage of 600V and a holding current of 30mA. It is rated for an average on-state current of 15A at a case temperature of 85°C. The component operates within a junction temperature range of -40°C to 125°C and offers a non-repetitive peak forward current capability of 170A.

Triacs Feature Summary

• Insulated base design for direct mounting to heat sinks without additional electrical isolation components
• High surge current handling capability suitable for inductive load switching
• Standardized pin configuration compatible with common thermal management solutions

Triacs Applications

• Industrial motor control systems requiring robust phase control
• Solid-state relays for AC power switching
• Lighting dimmer circuits for commercial and industrial fixtures

Triacs Procurement Notes

Verify the specific suffix code against official onsemi documentation to confirm exact electrical tolerances and packaging type. Ensure the procurement channel provides valid traceability certificates if required for aerospace or medical compliance. Confirm that the requested quantity matches the manufacturer's standard reel or tube specifications to avoid handling discrepancies during assembly.

Triacs Selection Notes

Select this component when a thermally isolated SCR is required for high-current AC regulation. Compare the 15A continuous rating against the application's RMS current requirements including derating factors for ambient temperature. Evaluate the 600V blocking voltage against the peak line voltage plus transient spikes to ensure adequate safety margins for the specific circuit topology.

Triacs Part Context
