MAC210A8G

Triacs Overview

The MAC210A8G is a bidirectional triac manufactured by Littelfuse, designed for AC power control applications. It features an on-state RMS current rating of 10 A and a repetitive peak off-state voltage (VDRM) of 600 V. The device is housed in a TO-220AB-3 package with through-hole mounting. Key electrical parameters include a maximum non-repetitive peak on-state current of 150 A, a holding current maximum of 40 mA, and a gate trigger voltage of 2.5 V. It operates within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Bidirectional AC switching capability for phase control applications
• Glass-passivated junctions for parameter stability and reliability
• Integrated thermal design suitable for high-current loads

Triacs Applications

• Lighting dimmers and intensity controls
• Solid-state relays for AC load switching
• Motor speed control circuits

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and variant selection. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Cross-reference the component marking with official Littelfuse documentation to prevent counterfeit substitution during sourcing.

Triacs Selection Notes

Select this component when a 10 A RMS current capacity at 600 V blocking voltage is required in a TO-220 package. Ensure the application's peak inrush currents remain below the 150 A non-repetitive limit. Verify that the gate drive circuit can supply the specified 2.5 V trigger voltage and 75 mA gate current reliably across the operating temperature range.

Triacs Part Context

This part belongs to the Littelfuse MAC series of general-purpose triacs. The 'A' suffix typically denotes the voltage rating class, while '8G' indicates the specific package type and lead finish configuration. It serves as a standard solution for industrial and consumer AC power regulation tasks requiring robust thyristor performance.

Triacs Replacement Considerations

Consult the official Littelfuse replacement guide for direct equivalents. Generic replacements must match the 10 A/600 V ratings and TO-220-3 footprint. Verify pinout compatibility and thermal resistance characteristics before substituting.
