Fast Turn-off Thyristors

The chips are processed with Complete Diffusion Technology and have internal amplifying gate structure. The thyristors can operate under conditions of fast turn-on and high rate of rise of on-state current (di/dt), and they possess excellent electrical dynamic characteristics such as low switching loss and fast turn-off time. The devices are suitable for single- or double-sided cooling. At case temperature of 55°C, the forward current rating IFAV ranges from 400A to 4800A, and the range of reverse blocking voltage VRRM is 1200V to 2800V. The typical applications for fast turn-off thyristors include inductive heating, electric welding, inverters and AC motor speed control.
