Description
The SPT312 reverse blocking thyristor is suitable for inverter applications up to
200Hz. The silicon junction is manufactured by the proven multi-diffusion process
and utilizes the exclusive eight (8) arms involute gate structure for lower switching

losses.
The design utilizes the revolutionary "Light Silicon Sandwich" or LSS technology,
a new termination technique which eliminates heavy refractory metal as a
substrate but still employs the alloyed anode interface necessary for high surge
current duty. The light weight plastic package allows the insertion of liquid
cooled chillers closer to the silicon junction. Copper inserts can be supplied for
