MAC228A10

Triacs Overview

The MAC228A10 is a sensitive gate triac from the MAC228A series, designed for full-wave AC load control in industrial and consumer applications. It features an 8 A RMS on-state current rating at 80°C case temperature and supports peak repetitive off-state voltages up to 800 V. The device utilizes a TO-220 package with thermowatt construction for efficient heat dissipation. Key electrical parameters include a maximum on-state voltage of 1.8 V, a holding current of 15 mA, and a gate trigger current of 10 mA. It operates within a junction temperature range of -40°C to 110°C.

Triacs Feature Summary

• Sensitive gate triggering capability supporting three modes for sinking current sources and four modes for sourcing current drive circuits.
• Diffused and glass-passivated junctions ensure parameter uniformity and operational stability across operating conditions.
• Center gate geometry promotes uniform current spreading within the silicon structure.

Triacs Applications

• Appliance controls
• Heater controls
• Motor controls

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging format and compliance status. The standard bulk configuration typically contains 500 units per tube. Confirm RoHS compliance requirements prior to finalizing procurement specifications.

Triacs Selection Notes

Select this component based on the required blocking voltage level, as the series offers ratings from 200 V to 800 V. Ensure the gate drive circuit matches the sensitive gate characteristics, specifically the 10 mA trigger current requirement. Verify thermal management capabilities align with the specified RMS current derating curves for the intended application environment.

Triacs Part Context

This part belongs to the MAC228A series of silicon bidirectional thyristors manufactured by onsemi. The series provides a range of voltage ratings including 200 V, 400 V, 600 V, and 800 V variants, all sharing the same 8 A RMS current capacity and TO-220 package style.

Triacs Replacement Considerations

Cross-reference with other sensitive gate triacs offering identical 800 V blocking voltage and 8 A RMS current ratings. Verify compatibility regarding gate trigger current thresholds and physical mounting dimensions before substitution.
