The BTA330-800BTQ with Triacs 3Q Hi-Com Triac is a 3-Quadrant Triac Driver manufactured by WeEn Semiconductor. It is designed for applications where mains power needs to be switched on and off or dimmed, such as lighting, heating, air conditioning, motors, and pumps. The device features a 400V blocking voltage, a 800V triggering voltage, and a 100A continuous on-state current. It also features 2 independent output channels, enabling it to switch two loads independently. Additionally, the device provides reliable triggering even at low temperatures, with a low minimum trigger current of 50mA. It is package in a TO-92 package, making it suitable for many applications.
