Protection against degradation of the edge contour in fast-ionization dynistors

详细

The results of studying silicon semiconductor devices with nanosecond turning-on times, that is, fast-ionization dynistors (FIDs), are presented. The effect of an abrupt increase in the leakage current that flows through an FID upon blocking of the power voltage after the termination of a train of switched pulses is discovered and described. It is shown that under certain conditions this effect may result in the destruction of the FID. Methods for modifying FIDs are presented that allow stabilization of the leakage current.
