Overview
The ACST610-8T is a logic-level sensitive gate TRIAC manufactured by STMicroelectronics, designed for general-purpose AC switching applications. It operates in a TO-220 through-hole package and supports an RMS on-state current of 6 A with a maximum non-repetitive surge current of 45 A at 50 Hz. The device features a rated repetitive peak off-state voltage of 800 V and a maximum gate trigger voltage of 1 V. It requires a maximum gate trigger current of 10 mA, enabling direct microcontroller interfacing. The component functions within a junction temperature range of -40°C to 125°C and complies with RoHS3 standards.
Feature Summary
- Logic-level sensitive gate architecture allows direct drive from microcontrollers with minimal gate current requirements.
- High commutation capability suitable for resistive loads without requiring external snubber circuits.
- Three-quadrant operation provides flexibility in triggering configurations for AC control systems.
Applications
- On/off or phase angle control in general purpose AC switching circuits
- Residential appliance motor and valve management
- Lighting dimmer implementations
Procurement Notes
Verify the specific ordering suffix to confirm the TO-220 package configuration and lead-free compliance status. Ensure the selected variant matches the required voltage rating and thermal dissipation needs for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a 6 A RMS current capacity and 800 V blocking voltage are sufficient for the load. The low 10 mA gate trigger current makes it suitable for designs prioritizing direct MCU integration without additional driver stages. Verify that the TO-220 thermal performance meets the system's heat dissipation requirements under continuous operation.
Part Context
This part belongs to the ACS™/A.S.D® series of AC switches from STMicroelectronics. It shares design characteristics with other logic-level TRIACs like the T610T-8T but utilizes A.S.D. technology for enhanced overvoltage protection and commutation reliability in residential and industrial AC control environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate equivalent logic-level TRIACs with matching 6 A current and 800 V voltage ratings only after verifying pinout compatibility and thermal specifications.
