Excellent unidirectional switches for phase control applications such as heating and motor speed controls. Standard phase control SCRs are triggered with few milliamperes of current at less than 1.5V potential. Features include glass-passivated junctions, voltage capability up to 1000V, and surge capability up to 350A. Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage. Typical applications are AC solid-state switches, industrial power tools, exercise equipment, white goods, and commercial appliances.
