Silicon Carbide Thyristor Wafer from China
Unmounted silicon carbide wafers designed for fabricating high-power thyristors used in industrial motor controls and power grids. These wafers meet the subheading criteria for thyristor chips under 8541.30.00.40 as they are unmounted semiconductor dice in wafer form prior to dicing. They enable high-voltage switching applications due to their superior thermal management.
