MAC997B8RL1G

Triacs Overview

The MAC997B8RL1G is a sensitive gate triac manufactured by onsemi, housed in a TO-92 package. It features a maximum repetitive peak off-state voltage of 600V and an RMS on-state current rating of 0.8A. The device operates as a four-quadrant logic level triac with a maximum DC gate trigger current of 5mA and a maximum DC gate trigger voltage of 2V. Key electrical characteristics include a holding current of 10mA, a non-repetitive peak on-state current of 8A at 50Hz, and a critical rate of rise of off-state voltage of 20 V/us. The component supports a maximum junction temperature of 125°C.

Triacs Feature Summary

• Sensitive gate design enabling direct interface with low-power logic circuits
• Four-quadrant operation for reliable triggering across all gate polarities
• Logic level compatibility with standard TTL and CMOS outputs

Triacs Applications

• Lighting control systems including dimmers and switches
• Small AC motor speed control applications
• Solid state relay output stages
• Heater control circuits

Triacs Procurement Notes

Verify the specific suffix RL1G to confirm tape and reel packaging requirements against your assembly line specifications. Ensure that the ordering part number matches the exact sensitivity class and package variant required for the design. Cross-reference the manufacturer's latest datasheet to confirm compliance status and any recent revisions to the mechanical drawings or electrical limits before finalizing procurement.

Triacs Selection Notes

Select this component when a compact TO-92 solution is required for low-current AC switching applications. The 600V blocking voltage suits general purpose mains-powered devices. The sensitive gate characteristic simplifies driver circuit design by reducing the required drive current. Verify that the 0.8A RMS current rating meets the load requirements and consider thermal management constraints inherent to the small plastic package.

Triacs Part Context

This part belongs to the MAC997 series of sensitive gate triacs from onsemi. The series offers various voltage ratings and packaging options to suit different power levels. The MAC997B8RL1G specifically denotes the 600V version in a through-hole TO-92 package supplied in reel format. This family is widely used in consumer electronics for basic AC control tasks due to its cost-effectiveness and ease of integration.

Triacs Replacement Considerations

Compatible substitutes include the MAC997B8 and MAC997B8G. These variants share identical electrical specifications but may differ in packaging quantity or RoHS compliance status. Verify that the alternative part number maintains the same RL1G reel specification if automated placement is required.
