MAC16D

Triacs Overview

The MAC16D is a silicon bidirectional thyristor (triac) designed for high-performance full-wave AC control applications requiring high noise immunity and commutating di/dt. It features a peak repetitive off-state voltage of 400 V and an on-state RMS current rating of 16 A at 80°C case temperature. The device supports a peak non-repetitive surge current of 150 A and operates within a junction temperature range of -40°C to +125°C. Electrical characteristics include a maximum gate trigger current of 50 mA, a holding current of 50 mA, and a minimum critical rate of rise of off-state voltage (dv/dt) of 500 V/µs at 125°C. It utilizes an industry-standard TO-220 package.

Triacs Feature Summary

• High noise immunity with a minimum dv/dt rating of 500 V/µs at 125°C
• High commutating di/dt capability of 9.0 A/ms minimum at 125°C
• Uniform gate trigger currents across three quadrants
• Minimizes the need for snubber networks for protection

Triacs Applications

• High performance full-wave AC control
• Industrial motor speed controls
• Solid state relays

Triacs Procurement Notes

Verify component authenticity by checking the marking diagram for the 'x' suffix corresponding to the specific voltage rating. Confirm RoHS compliance status as indicated in the ordering information section. Ensure the TO-220 package matches the required thermal resistance specifications for the application environment.

Triacs Selection Notes

Select the MAC16D variant specifically when a 400 V blocking voltage is required, distinguishing it from the MAC16M (600 V) and MAC16N (800 V). Consider the 16 A RMS current rating against the expected load requirements and derating curves provided in the datasheet. Evaluate the thermal management needs based on the junction-to-case thermal resistance value.

Triacs Part Context

The MAC16D belongs to the MAC16 family of silicon bidirectional thyristors manufactured by onsemi. This series includes variants with different blocking voltages, such as the MAC16M and MAC16N. All devices share the same physical package and general electrical structure but are differentiated by their peak repetitive off-state voltage ratings.

Triacs Replacement Considerations

Direct substitutes within the same family include the MAC16M and MAC16N, which offer higher blocking voltages of 600 V and 800 V respectively while maintaining the same current ratings and package type.
