.The BTA16-800SW with TO-220AB-3 TRIACs ROHS manufactured by Kang Yang is a 3 terminal AC switch designed to handle the power for applications such as controlling motors, lighting, and other AC loads up to 800 VAC. It is made up of a sensitive gate Triac in a TO-220AB-3 plastic package, which is designed formedium-power switching and phase control applications with high thermal stability and a wide range of temperatures. It has a low power gate current with a turn on trigger current on the order of a few milliamps, and the triac is RoHS compliant. Features include minimal board space and low thermal resistance, low power dissipation, and a high current capability. This makes it ideal for a wide range of applications, such as HID lighting, AC motor speed controls, and static relays.
