The ACST310-8BTR is an advanced, high-voltage TRIAC specifically designed for AC power switching in industrial and consumer applications. It features an 800V blocking voltage, making it well-suited for operation on high-voltage AC mains, and a continuous RMS current rating of 10A, enabling it to control various loads such as motors, pumps, lighting circuits, and home appliances.
This TRIAC integrates overvoltage protection, ensuring reliable performance under harsh electrical conditions, including surges and transients from inductive loads. Its snubberless design enhances immunity to electrical noise and simplifies circuit design by eliminating the need for external snubber components. Additionally, the high dV/dt capability allows for robust operation in noisy environments without false triggering.
Housed in a DPAK (TO-252) surface-mount package, the ACST310-8BTR offers excellent heat dissipation and is compatible with automated soldering processes, making it ideal for compact designs. It is used extensively in home automation systems, motor controls, power tools, HVAC systems, and other AC load-switching applications. This TRIAC is optimized for energy-efficient switching, helping to extend product lifespan while reducing overall power consumption.
