MAC9NG

Triacs Overview

The Littelfuse MAC9NG is a surface mount triac housed in a TO-220AB package. It features a peak repetitive off-state voltage of 800V and an on-state RMS current rating of 8.0A at 100°C. The device supports a peak non-repetitive surge current of 80A and operates within a junction temperature range of -40°C to +125°C. Electrical characteristics include a maximum peak on-state voltage of 1.6V, a gate trigger current up to 50mA, and a holding current of 50mA. Thermal resistance from junction to case is 2.2°C/W, while junction-to-ambient resistance is 62.5°C/W.

Triacs Feature Summary

• Designed for high performance full-wave AC control applications requiring high noise immunity
• Provides high commutating di/dt capability to minimize snubber networks for protection
• Features uniform gate trigger currents across three quadrants

Triacs Applications

• High performance full-wave AC control circuits
• Applications requiring high noise immunity
• Systems demanding high commutating di/dt ratings

Triacs Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm voltage ratings and compliance status. Ensure that ordering details match the required blocking voltage and thermal specifications for the intended application environment. Confirm RoHS compliance and Pb-Free status through manufacturer datasheets prior to procurement.

Triacs Selection Notes

Select the MAC9NG when an 800V blocking voltage and 8.0A RMS current are required in a TO-220AB surface mount package. Consider the device's high dV/dt immunity and commutating di/dt capabilities for circuits where snubber networks must be minimized. Evaluate thermal management requirements based on the specified junction-to-case and junction-to-ambient thermal resistances.

Triacs Part Context

The MAC9NG belongs to the MAC9xG series, which includes variants with different voltage ratings such as the MAC9DG (400V) and MAC9MG (600V). All devices in this series share the same TO-220AB package and general electrical characteristics, differing primarily in their peak repetitive off-state voltage ratings.

Triacs Replacement Considerations

MAC9DG and MAC9MG are direct functional substitutes within the same series, sharing identical packages and current ratings but offering lower voltage ratings of 400V and 600V respectively.
