Fast Switch Thyristor

Description:

Fast switch thyristor, with the same structure and symbol of phase control thyristor, while the better static characteristics, especially dynamic characteristics is required by the high frequency application of rectification, chopping, inverter and frequency conversion circuit. The dynamic parameters of the fast thyristor are fast turn-on speed and turn-on expansion speed, less reverse recovery charge, and short turn-off time, high critical rise rate of on-state current (di/dt) and critical rate of rise of off-state voltage (dv/dt). The rated current of the fast thyristor within the rated frequency does not decrease or decreases a little when frequency increasing.

The fast switch thyristor manufacturing standard and processing technology of RUNAU Electronics was introduced from USA since 1980s, as a pioneer of manufacturing thyristor in China, the technical team of RUNAU had acquired the cutting-edge knowledge and ample manufacturing experience for more than 30 years. On basic of traditional manufacturing process, the talent technicians of RUNAU Electronics had developed the art-of-state technology in manufacturing thyristor with advantage features of European products, the quality and performance are improved greatly, more big wins achieved in the power electronics applications, and more value was created for partners.

Introduction:

1. Chip

The thyristor chip manufactured by RUNAU Electronics is sintered alloying technology employed. The silicon and molybdenum wafer was sintered for alloying by pure aluminum (99.999%) under high vacuum and high temperature environment. The administration of sintering characteristics is the key factor to affect the quality of thyristor. The know-how of RUNAU Electronics in addition to manage the alloy junction depth, surface flatness, alloy cavity as well full diffusion skill, ring circle pattern, special gate structure. Also the special processing was employed to reduce the carrier life of the device, so that the internal carrier recombination speed is greatly accelerated, the reverse recovery charge of the device is reduced, and the switching speed is improved consequently. Such measurements were applied to optimize the fast switching characteristics, on-state characteristics, and surge current property. The performance and conduction operation of thyristor is reliable and efficient.

2. Encapsulation

By strict controlling of flatness and parallelism of molybdenum wafer and external package, the chip and molybdenum wafer will be integrated with external package tightly and completely. Such will optimize the resistance of surge current and high short circuit current. And the measurement of electron evaporation technology was employed to create a thick aluminum film on silicon wafer surface, and ruthenium layer plated on molybdenum surface will enhance thermal fatigue resistance greatly, the work life time of fast switch thyristor will be increased significantly.
