MAC997B6G

Triacs Overview

The MAC997B6G is a three-terminal bidirectional triac switch from onsemi, designed for logic-sensitive gate applications. It features a maximum holding current of 800 mA and a repetitive peak off-state voltage rating of 400 V. The component utilizes a TO-92 (TO-226) through-hole package configuration. It operates within a junction temperature range of -40°C to +110°C, ensuring reliable performance in various electronic circuits requiring phase control or switching functions.

Triacs Feature Summary

• Logic-sensitive gate structure enables direct interface with standard logic outputs
• Bidirectional conduction capability supports AC load switching applications
• Robust thermal design accommodates high operating temperatures up to 110°C

Triacs Applications

• Lighting dimmer controls
• Motor speed regulation systems
• Thermostat heating control circuits

Triacs Procurement Notes

Verify the specific ordering suffix '6G' corresponds to the required tape-and-reel or bulk packaging format as defined by onsemi standards. Confirm that the TO-92 lead form matches the target PCB footprint requirements. Ensure compliance with RoHS directives if environmental regulations apply to the final assembly process.

Triacs Selection Notes

Select this component when a low-power triac with logic-compatible gate sensitivity is required for AC switching tasks. The 400V rating suits general-purpose mains voltage applications below higher voltage thresholds. Consider the TO-92 package constraints regarding thermal dissipation and physical space limitations compared to larger industrial packages.

Triacs Part Context

This device belongs to the MAC99 series of triacs manufactured by onsemi. It represents a standard solution for consumer electronics and light industrial control where compact sizing and cost-effectiveness are prioritized alongside basic switching performance characteristics typical of the broader triac family.

Triacs Replacement Considerations

Consult official cross-reference lists for equivalent parts such as the MAC97A6 or similar logic-level triacs with matching voltage and current ratings. Verify pinout compatibility and thermal characteristics before substituting to ensure circuit integrity.
