MAC15SM

Triacs Overview

The MAC15SM is a sensitive gate triac from onsemi, housed in a TO-220AB package. It is rated for 600V blocking voltage and 15A RMS current. The device features high immunity to dv/dt of at least 25 V/µs at 110°C and high commutating di/dt of 8.0 A/ms minimum at 110°C. Maximum values for gate trigger current (IGT), gate trigger voltage (VGT), and holding current (IH) are specified to ensure reliable operation.

Triacs Feature Summary

• Sensitive gate architecture for low power triggering
• High dv/dt noise immunity for stable switching
• Robust commutating di/dt capability
• Silicon bidirectional thyristor construction

Triacs Applications

• AC power control circuits
• Lighting dimmer applications
• Motor speed control systems
• Heater regulation devices

Triacs Procurement Notes

Verify the specific suffix 'SM' against the official datasheet to confirm pinout and thermal characteristics. Check component status as some listings indicate obsolescence. Ensure the TO-220AB package matches the design requirements. Confirm that the sensitive gate specifications align with the driving circuit capabilities before finalizing the procurement order.

Triacs Selection Notes

Select this component when low gate drive power is required alongside high current handling. The sensitive gate feature allows for efficient triggering with minimal gate current. Consider the 600V rating for general AC line applications. Evaluate the thermal performance within the TO-220AB package for the expected load conditions.

Triacs Part Context

This part belongs to the family of sensitive gate triacs designed for industrial and commercial AC control. It offers a balance of high current capacity and easy triggering. The TO-220AB package provides robust mechanical mounting and heat dissipation suitable for medium-power applications.

Triacs Replacement Considerations

Consult official cross-reference guides for direct replacements. Verify that any substitute maintains the 600V rating, 15A current capacity, and sensitive gate characteristics. Ensure the replacement package is compatible with the existing PCB footprint and thermal management strategy.
