Triacs datasheet and documents for MAC212A8G
Triacs Overview
The MAC212A8G is a bidirectional thyristor (triac) from Littelfuse, designed for full-wave AC control applications. It features a TO-220AB package with Pb-free construction and Case 221A-07 styling. The device supports a peak repetitive off-state voltage of 600V and an on-state RMS current of 12A at TC = +85°C. It guarantees gate triggering in all four quadrants and utilizes diffused, glass-passivated junctions for parameter stability. Thermal resistance from junction to case is 2.0 °C/W, with a maximum operating junction temperature range of -40°C to +125°C.
Triacs Feature Summary
- Guaranteed gate triggering across all four operational quadrants
- Diffused and glass-passivated junctions for enhanced parameter uniformity
- Thermowatt construction providing low thermal resistance and high heat dissipation
Triacs Applications
- Light dimmers
- Motor controls
- Heating controls
- Power supplies
Triacs Procurement Notes
Verify the specific part number suffix against official Littelfuse documentation to confirm lead-free status and packaging configuration. Ensure that the selected component meets the required electrical ratings for the intended application environment. Cross-reference datasheet revisions to confirm current specifications before finalizing procurement orders.
Triacs Selection Notes
Select the MAC212A8G when a 12A RMS current rating and 600V blocking voltage are required for AC switching tasks. Consider the TO-220AB package for through-hole mounting and adequate heat sinking capabilities. Evaluate the gate trigger characteristics to ensure compatibility with the driving circuitry requirements for reliable turn-on in all quadrants.
Triacs Part Context
The MAC212A8G belongs to the MAC212 series of triacs manufactured by Littelfuse. This series includes variants with different voltage ratings, such as the MAC212A10 which offers 800V blocking capability. All devices share similar physical dimensions and thermal characteristics within the TO-220AB form factor.
Triacs Replacement Considerations
The MAC212A10 serves as a higher voltage alternative within the same series, offering 800V blocking capability while maintaining identical current ratings and package dimensions. Verify pinout compatibility and thermal performance when substituting between these variants.
