SEMiX302KT16S — 1600 V / 300 A Thyristor / Rectifier Module
The SEMiX302KT16S by Semikron is a high-power thyristor/rectifier module engineered for demanding industrial and commercial power electronics. Featuring a 1600 V blocking voltage (VRRM / VDRM) and a 300 A average current rating, this module is built to handle high current, high voltage environments such as AC/DC motor control, soft starters, and power supply input bridges. It combines high surge capability, robust thermal management, and reliable semiconductor package construction — making it a strong candidate for heavy duty applications.
In applications requiring durability under load, the SEMiX302KT16S excels: its thyristor and diode chips are soldered directly to an isolated substrate, allowing efficient conduction and good heat transfer. The module supports high peak and surge currents (ITSM ~ 9300 A for 10 ms, i²t ratings in the 10 ms range), making it resilient in transient overload conditions. Thermal resistance values are low, and the module operates over wide temperature ranges.
Efficiency and reliability are enhanced via low forward voltage drop (typical on-state voltage around 1.7 V at designated currents), high blocking voltage margin, and robust isolation. The rugged SEMiX2S housing with 17 mm terminal height provides reliable mounting and mechanical stability. For equipment designers, this module offers consistency, reduced external component stress, and suitability for both new installations and retrofits in industrial systems.
