Overview
The ACST830-8GTR is a standard Triac from the ACS series, manufactured by STMicroelectronics. It features an 8 A RMS on-state current and an 800 V repetitive peak off-state voltage. The device has a maximum gate trigger voltage of 1 V and a holding current of 30 mA. Non-repetitive surge currents are rated at 80 A for 50 Hz and 84 A for 60 Hz. It operates within a junction temperature range of -40°C to 125°C and is housed in a surface-mount D2PAK (TO-263) package.
Feature Summary
- Integrates a high-voltage clamping device to absorb inductive turn-off energy and withstand line transient voltages.
- Provides improved commutating dV/dt and dI/dt capabilities compared to conventional Triacs.
- Sensitive gate option enables direct drive from microcontrollers without additional interface circuitry.
Applications
- Washing machine drum motor control
- Refrigerator compressor control
- Dishwasher pump motor control
Procurement Notes
Verify the specific ordering suffix GTR against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure compliance with RoHS3 standards and check for any recent Product Change Notifications regarding lead modifications or carrier tape design improvements before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring robust overvoltage protection and high noise immunity for AC load switching. The integrated clamping structure makes it suitable for environments subject to electrical transients. Verify that the required gate drive voltage remains below the 1 V maximum limit to ensure reliable triggering from low-power logic sources.
Part Context
This part belongs to the ACST Series of 800 V AC Switches, which serve as rugged alternatives to conventional Triacs. The series spans current ratings from 4 A to 16 A and includes various packages such as DPAK, D²PAK, TO-220, and TO-220FP. These devices are engineered to help appliances meet IEC 61000-4-4 and -4-5 electromagnetic compatibility standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official selection guide for compatible devices within the same current and voltage ratings.
