125 mm LSS PLASTIC PACKAGED CONVERTOR THYRISTOR OF 5000V/4600AMPS RATING DEVELOPED FOR THE FIRST TIME IN INDIA BY RUTTONSHA IN COLLABORATION WITH S.P.C.O.
- 4600A, 5000V
- 270kA Pulse Current Capability
- 20kA/mS di/dt Pulse Capability
- Low Power Gate Driver
The SPT411A thyristor is optimized for pulse power applications. It features a highly intedigitated cathode / pilot gate combinations which enable extremely high pulse power di/dt driven with low gate power.
The design utilizes a 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. This light weight plastic package allows the insertion of liquid cooled chillers. Copper inserts can be supplied for adjoining commercially available flat surfaced heat dissipators.
