CRRC Times Semiconductor KK1800A/1800V Fast Switching Thyristor (SCR)
The CRRC Times Semiconductor KK1800A/1800V is a premium-grade, disc-type (capsule/puck) fast switching thyristor engineered for high-power industrial applications. Manufactured by the industry-leading Zhuzhou CRRC Times Semiconductor Co., Ltd., this robust Silicon Controlled Rectifier (SCR) delivers exceptional reliability and efficiency in power conversion, motor control, and induction heating systems. It features a high average on-state current of 1800A and a repetitive peak voltage rating of 1800V, ensuring optimal performance under demanding electrical loads. With a rapid turn-off time of 330 μs and high critical rates of rise for both current (di/dt ≥1000 A/μs) and voltage (dv/dt ≥1000 V/μs), the KK1800A/1800V guarantees precise control and superior dynamic characteristics in high-frequency switching environments.
