MAC212A10FP

Triacs Overview

The MAC212A10FP is a four-quadrant logic level TRIAC manufactured by onsemi, designed for power control applications. It features an 800V repetitive off-state voltage and an 8A RMS on-state current capability. The device utilizes an isolated TO-220 package (FULL PACK-3) to facilitate heat dissipation and mounting. Key electrical parameters include a maximum DC gate trigger current of 50 mA and a maximum DC gate trigger voltage of 2 V. The component operates within a temperature range of -40°C to +125°C and exhibits a maximum on-state voltage of 2 V.

Triacs Feature Summary

• Four-quadrant logic level triggering for versatile gate drive compatibility
• Isolated TO-220 package design for efficient thermal management and ease of installation
• Glass passivated junctions to ensure parameter uniformity and operational stability

Triacs Applications

• Motor control systems
• Heating control circuits
• Power supply units

Triacs Procurement Notes

Verify the specific datasheet version from onsemi or authorized distributors to confirm compliance with RoHS directives, as historical data indicates non-compliance for some variants in this series. Ensure the ordering suffix matches the required voltage rating and package type. Cross-reference part numbers carefully to distinguish between standard and A-series devices, as functional differences may exist regarding triggering modes.

Triacs Selection Notes

Select this component when an 800V blocking voltage and 8A continuous current are required in a high-power isolation environment. The logic-level input simplifies driver circuitry compared to standard TRIACs. Verify that the application's peak surge currents remain within the specified non-repetitive limits. Consider the thermal resistance of the TO-220 package relative to the expected ambient temperature and load duty cycle.

Triacs Part Context

This part belongs to the MAC218FP and MAC218AFP series, which share common structural characteristics but differ in triggering quadrant support. The MAC218A10FP serves as a direct reference for the physical package and general electrical envelope. The 'A' suffix typically denotes four-quadrant sensitivity, whereas non-A variants may offer three-quadrant triggering.

Triacs Replacement Considerations

Direct substitutes include other 800V, 8A TRIACs in TO-220 packages from manufacturers such as Littelfuse or STMicroelectronics. Verify pinout compatibility and gate trigger specifications before substitution. Equivalent parts must match the isolated case configuration if electrical isolation from heatsinks is required.
