270kA Pulse Current Capability
20kA/mS di/dt Pulse Capability
Low Power Gate Driver
The SPT411A thyristor is enhanced for pulse power applications. It structures a highly interdigitated cathode/pilot gate combinations which empower extremely high pulse power di/dt driven with low gate power.
The design develops a revolutionary “Light Silicon Sandwich” or LSS technology, a new conclusion technique which removes substantial refractory metal as a substrate but still employs the alloyed anode interface essential for high surge current duty. This light weight plastic platform allows the insertion of liquid cooled chillers. Copper inserts can be supplied for adjoining commercially available flat surfaced heat dissipaters.
