MAC12MG

Triacs Overview

The Littelfuse MAC12MG is a sensitive gate triac rated for 800V peak repetitive off-state voltage and 12A RMS on-state current. It operates within a junction temperature range of -40°C to +125°C and features a TO-220AB package. Key electrical parameters include a maximum peak on-state voltage of 1.85V, a maximum holding current of 40mA, and a maximum gate trigger current of 35mA across all three quadrants. The device supports a non-repetitive surge current of 100A and offers high commutating di/dt immunity of at least 6.5 A/ms.

Triacs Feature Summary

• Sensitive gate design enabling uniform triggering in Quadrants I, II, and III
• High noise immunity with a minimum critical rate of rise of off-state voltage (dv/dt) of 250 V/µs
• Robust commutation performance with a minimum di/dt rating of 6.5 A/ms

Triacs Applications

• Full-wave AC control applications requiring high noise immunity
• Industrial motor speed control systems
• Solid-state relay circuits

Triacs Procurement Notes

Verify the specific ordering suffix 'G' confirms lead-free compliance and RoHS status as documented in the manufacturer's datasheet. Confirm the package style matches the required TO-220AB dimensions for your PCB layout. Ensure the selected part number corresponds to the 800V blocking voltage variant designated by the 'N' series code.

Triacs Selection Notes

Select this component when an 800V blocking voltage and 12A continuous current rating are required. The sensitive gate characteristic allows for lower drive power compared to standard gate devices. Verify that the thermal management solution can maintain the junction temperature below 125°C under full load conditions.

Triacs Part Context

The MAC12MG belongs to the MAC12x family of thyristors, which includes variants with different voltage ratings such as the MAC12D (400V) and MAC12N (800V). This specific model represents the high-voltage option within the industry-standard TO-220 form factor designed for general-purpose AC switching.

Triacs Replacement Considerations

MAC12NG serves as a direct equivalent within the same product family offering identical electrical characteristics and pinout configuration.
