ACST610-8T Description

The ACST610-8T from STMicroelectronics is a high-performance TRIAC (Triode for Alternating Current) designed for robust switching applications. Part of the ACS™/A.S.D® series, this device features an 800V off-state voltage and a 6A RMS on-state current, making it suitable for medium-power AC load control. Its sensitive gate requires only 1V (max) trigger voltage and 10mA (max) trigger current, ensuring efficient and reliable triggering with low-power control circuits. Packaged in a TO-220 through-hole format, it is ideal for industrial and consumer applications demanding high voltage handling and thermal performance.

ACST610-8T Features

• High Voltage Rating: 800V off-state voltage ensures reliability in demanding AC line applications.
• Low Gate Triggering: 1V/10mA max gate requirements enable compatibility with low-power microcontrollers and logic circuits.
• Robust Surge Handling: Non-repetitive surge current up to 45A (50Hz)/47A (60Hz) for transient overload protection.
• Thermal Efficiency: TO-220 package facilitates heat dissipation, critical for sustained high-current operation.
• Compliance: ROHS3 compliant, REACH unaffected, and EAR99 classified for global regulatory adherence.
• Reliable Performance: 25mA max holding current ensures stable conduction under varying load conditions.

ACST610-8T Applications

• Home Appliances: AC motor control in washing machines, fans, and vacuum cleaners.
• Industrial Systems: Solid-state relays, contactors, and industrial heating controls.
• Lighting: Dimming circuits for incandescent and LED drivers.
• Power Tools: Speed control in drills and saws.
• Automotive: Auxiliary power switching in electric vehicles (EVs) and charging systems.

Conclusion of ACST610-8T

The ACST610-8T stands out for its high voltage tolerance, low gate drive requirements, and excellent surge resilience, making it a versatile choice for AC switching applications. Its TO-220 packaging and compliance with environmental standards further enhance its suitability for both industrial and consumer electronics. Engineers will appreciate its balance of performance, reliability, and ease of integration, particularly in designs requiring efficient power management and robust transient protection.
