Description
Summary:For the high requirements of the thyristor for pulse switch on di/dt tolerance, the turn-on process and di/dt failure mechanism of thyristor are described. The 6-inch thyristor for pulse switch has been developed by choosing appropriate parameters of silicon wafer, adjusting P-base impurity profile, optimizing gate graph, and using double negative angle bevel. The experiment verifies that the pulse peak current can reach 300 kA, the di/dt rating is more than 3 000 A / s, and the thyristor has good stability and reliability.
