Product Description
The STMicroelectronics ACST830-8GTR is a surface mount 3-pin TRIAC semiconductor device designed for efficient switching of alternating current (AC) in industrial and electronic applications. It offers a rated average on-state current of 8 amperes and a repetitive peak reverse voltage rating of 800 volts, making it suitable for handling moderately high power circuits requiring reliable AC switching.
This TRIAC features a low gate trigger voltage of 1 volt and a maximum gate trigger current of 30 milliamperes, enabling sensitive gate triggering for efficient and simple control. The package type TO-263 ensures compatibility with modern PCB assembly processes, while its compact physical dimensions (10.4 mm length and 4.6 mm height) allow for optimized circuit footprint.
Designed with an embedded high voltage clamping structure, the ACST series can absorb inductive turn-off energy and withstand line voltage transients, enhancing device durability and safety in inductive load switching applications. It supports a wide operating temperature range from -40°C to 125°C, permitting use in harsh industrial environments.
This device has an 84-ampere surge current rating to manage transient load spikes effectively without damage. The single TRIAC configuration and 3-pin count simplify the electrical design and installation.
The ACST830-8GTR finds application in industrial motor controls, lighting systems, HVAC equipment, power supplies, and other alternating current loads where controlled switching is required. Its over-voltage protection capability further secures circuits against transient faults.
