MAC997A6G

Triacs Overview

The MAC997A6G is a sensitive gate triac manufactured by onsemi, designed for solid state relays and MPU interfaces. It features a four-quadrant logic level triggering capability suitable for circuits sourcing gate drives. The device utilizes an injection-molded TO-92 package, facilitating automatic insertion. Key electrical parameters include a blocking voltage of 400V, an RMS current of 0.8A, and a non-repetitive peak surge current of 8A. It operates within a temperature range of -40°C to +110°C, with a maximum holding current of 10mA and a gate trigger voltage of 2.5V.

Triacs Feature Summary

• Sensitive gate triggering in all four quadrants for versatile logic interface compatibility
• Injection-molded TO-92 package construction for cost-effective automated assembly
• High noise immunity with improved dv/dt characteristics at elevated temperatures

Triacs Applications

• Solid state relay switching
• Microprocessor unit (MPU) interfacing
• TTL logic circuit control

Triacs Procurement Notes

Verify the specific suffix 'G' against official datasheets to confirm lead-free status and RoHS compliance details. Confirm the manufacturer's current production status as discontinuance notices may affect long-term availability. Ensure the selected component matches the required 400V rating rather than higher voltage variants.

Triacs Selection Notes

Select this component when a low-cost, through-hole triac is needed for AC load control in consumer or light industrial applications. Verify that the 0.8A RMS current rating meets the load requirements. Consider the TO-92 package constraints regarding thermal dissipation and physical space compared to surface-mount alternatives.

Triacs Part Context

This part belongs to the MAC997 series of sensitive gate triacs from onsemi. It shares functional similarities with other models in the family but is distinguished by its specific voltage and current ratings. The series is widely used in general-purpose AC switching applications requiring reliable logic-level triggering.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with generic 400V, 0.8A sensitive gate triacs in TO-92 packages if necessary, ensuring matching electrical parameters.
