Due to capacity growth of inverter units in power semiconductor electronics high voltage and high current thyristors adapted for usage in series and parallel connection are in great demand nowadays.

Thyristors designed for parallel assemblies must have high adequacy of volt-amps diagramm in on-state, thyristor designed for usage in series connection assemblies must have high adequacy of reverce recovery characteristics. General requirement for all applications is presence of identical and preferably minimized temperature dependencies of the above mentioned characteristics.
