1600 V phase control thyristor disc Phase Control Thyristor 1600 V, 2200 A with 100 mm diameter and a height of 26 mm assembled in high reliable, robust and hermetic sealed ceramic housings. The T2200N thyristor disc is specially optimized for UPS-Bypass applications in terms of production effort and clamping force allowing same on state losses with smaller clamping systems. Our pressure contact chips in general provide best-in-class blocking stability and offers the highest current capability.
