MAC8SN

Triacs Overview

The MAC8SN is a sensitive gate triac from the MAC8S series, manufactured by onsemi. It features an 8 A RMS on-state current rating at 70°C and supports peak repetitive off-state voltages up to 800 V. The device handles a non-repetitive surge current of 70 A and operates within a junction temperature range of -40°C to +110°C. Key electrical parameters include a maximum gate trigger current of 5 mA, a holding current of 10 mA, and a peak on-state voltage of 1.85 V. It utilizes a TO-220 package with a thermal resistance of 62.5°C/W junction-to-ambient.

Triacs Feature Summary

• Sensitive gate design enables direct triggering by microcontrollers and logic circuits
• High immunity to dv/dt with a minimum rating of 25 V/µs at 110°C
• Uniform gate trigger currents specified across Quadrants Q1, Q2, and Q3

Triacs Applications

• Appliance controls
• Heater controls
• Motor controls
• Full wave AC load power switching

Triacs Procurement Notes

Verify the specific part number suffix against official documentation to confirm voltage ratings and compliance status. Confirm RoHS compliance and Pb-free packaging details directly with the manufacturer or authorized distributors before procurement. Ensure ordering specifications match the required blocking voltage for the intended application circuit.

Triacs Selection Notes

Select this component based on its 800 V blocking voltage capability and 8 A RMS current handling. Consider the sensitive gate requirement for low-power logic interfacing. Evaluate thermal management needs using the provided junction-to-ambient resistance values. Verify that the operating temperature range meets the environmental constraints of the target system.

Triacs Part Context

This device belongs to the MAC8S/D family of silicon bidirectional thyristors designed for industrial and consumer applications. The 'N' suffix specifically denotes the 800 V blocking voltage variant within the MAC8SD (400 V), MAC8SM (600 V), and MAC8SN (800 V) lineup. All variants share identical physical packages and general electrical characteristics except for the voltage rating.

Triacs Replacement Considerations

MAC8SDG and MAC8SMG are compatible in the same package but offer lower voltage ratings of 400 V and 600 V respectively.
