MAC8SNG

Triacs Overview

The Littelfuse MAC8SNG is a sensitive gate triac rated for 800 V peak repetitive off-state voltage and 8.0 A RMS on-state current at 70°C case temperature. It supports a non-repetitive surge current of 70 A and operates within a junction temperature range of -40°C to +110°C. The device features a maximum on-state voltage of 1.85 V, a gate trigger current up to 5.0 mA, and a holding current up to 10 mA. It utilizes a TO-220AB package with thermal resistance from junction to case at 2.2 °C/W.

Triacs Feature Summary

• Sensitive gate design enables triggering by microcontrollers and logic circuits
• Uniform gate trigger currents specified across quadrants Q1, Q2, and Q3
• High immunity to dv/dt with a minimum of 25 V/µs at 110°C
• High commutating di/dt capability of 8.0 A/ms minimum at 110°C

Triacs Applications

• Appliance controls
• Heater controls
• Motor controls
• Power switching applications

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact voltage rating and package style. Ensure that the procurement specifications match the required electrical parameters for the intended circuit design. Confirm compliance with RoHS standards if lead-free components are mandatory for the assembly process.

Triacs Selection Notes

Select this component based on the 800 V blocking voltage requirement and the 8 A RMS current capacity. Consider the thermal management needs given the junction-to-case thermal resistance. Verify that the gate trigger characteristics align with the driving logic levels available in the control circuitry.

Triacs Part Context

The MAC8SNG belongs to the MAC8SxG series of thyristors manufactured by Littelfuse. This series includes variants with different voltage ratings, such as the MAC8SDG (400 V) and MAC8SMG (600 V). All devices share similar physical packaging and general electrical characteristics tailored for AC load control.
