Abstract:
The new possibilities to improve dynamic characteristics of power thyristors and diodes are discussed on the basis of low temperature silicon chip connection and Mo-disc by means of sintering of silver paste. It is described that for fast thyristors with silicon chip diameter 56-100 mm sintering technology allows decreasing greatly turn-off time simultaneously with decrease of on-state voltage. Complex application of sinter technology and proton irradiation allows also producing single chip freewheeling diodes with exclusive soft reverse recovery characteristic.
