SPT312

SPT312 3000A, 4500V 100mm Thyristor Features 3000A, 4500V 40kA Pulse Current Capability Fast Turn-off Time Light Weight Package Package A=5.375in, B=3.204in, C=0.792in, D=0.2902in Notes - 1, 2 & 3 C D 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 adjoining commercially available flat surfaced heat dissipators.
