ACST610-8G

Overview

The ACST610-8GTR is a logic-level sensitive gate triac from the ACS/ACST power switch family, manufactured by STMicroelectronics. It features an 800 V repetitive off-state voltage and a maximum RMS on-state current of 6 A in a D2PAK surface-mount package. The device requires a maximum gate trigger current of 10 mA for activation, enabling direct microcontroller interfacing. It operates within a junction temperature range of -40°C to +125°C and includes integrated overvoltage protection capabilities.

Feature Summary

• Logic-sensitive gate structure allowing direct drive from low-power digital controllers
• Integrated high-voltage clamping device for absorbing inductive turn-off energy
• High immunity to electrical noise and fast transient bursts per IEC standards

Applications

• General purpose AC switching in home appliances
• Industrial system load control
• Compressor starter motor circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements for your target market. Cross-reference the full part number with official distributor catalogs to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when an 800 V rating and 6 A continuous current capacity are required for AC loads. The logic gate sensitivity simplifies driver circuit design by eliminating the need for high-current gate drivers. Consider the D2PAK package for thermal management needs in compact PCB layouts compared to through-hole alternatives.

Part Context

This device belongs to the ACS/ACST series built with Application Specific Discrete (ASD) technology. It is designed to replace traditional triacs by offering superior reliability and reduced bill-of-materials through integrated protection features. The series supports various mounting options including surface mount and through-hole packages.

Replacement Considerations

Check for equivalent parts within the same ACS/ACST family that share identical voltage and current ratings but offer different packaging options such as TO-220 or TO-247 for alternative mechanical integration requirements.
