MAC210A10

Triacs Overview

The MAC210A10 is a silicon bidirectional thyristor (Triac) designed for full-wave AC control applications. It features an 800 V peak repetitive off-state voltage and supports a 10 A RMS on-state current at a case temperature of +70°C. The device utilizes a TO-220AB package with flange mounting capabilities, offering a thermal resistance from junction to case of 2.0 °C/W. Gate triggering is guaranteed across all four quadrants, ensuring reliable operation with positive or negative gate signals relative to Main Terminal 1. The component operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Guaranteed gate triggering in all four operating quadrants for versatile control logic compatibility.
• Diffused and glass passivated junctions ensure parameter uniformity and long-term stability.
• Robust thermowatt construction provides low thermal resistance and high heat dissipation capacity.

Triacs Applications

• Light dimmers
• Motor controls
• Heating controls
• Power supplies

Triacs Procurement Notes

Verify the specific ordering suffix when purchasing. The standard part number refers to the non-rohs version, while the 'G' suffix indicates a lead-free package compliant with environmental standards. Confirm the package style matches the required PCB footprint, as the TO-220AB variant requires specific mounting considerations for the metal tab connection.

Triacs Selection Notes

Select the MAC210A10 over the MAC210A8 when the circuit requires a higher blocking voltage rating of 800 V instead of 600 V. Ensure the thermal management design accounts for the 10 A RMS current limit at a 70°C case temperature. Verify that the gate drive circuit can supply the maximum trigger current of 75 mA required for reliable turn-on in Quadrant IV operation.

Triacs Part Context

This component belongs to the MAC210 series of 10 Ampere Triacs manufactured by onsemi. The series includes variants with different voltage ratings, such as the 600 V MAC210A8. Both devices share identical current handling capabilities and physical packaging, differing primarily in their maximum off-state voltage specifications for various AC switching requirements.

Triacs Replacement Considerations

The MAC210A8 serves as a lower-voltage alternative within the same series if 600 V blocking is sufficient. Cross-reference with other 10 A, 800 V Triacs in the TO-220AB package from other manufacturers, ensuring matching IGT and IT(RMS) parameters are met for direct substitution.
