Type SPT401 thyristor is suitable for phase control applications such as for HVDC valves, static VAR compensators
and synchronous motor drives. A second generation pilot gate and a unique orientation of emitter shorts are emoloyed
which promote the lateral expansion of conducting plasma resulting in lower spreading losses and high dv/dt
withstand. It is supplied in a reliable plastic light weight package

LSS technology, a new termination technique which eliminates heavy refractory
metal as a substrate while retaining an alloyed anode interface necessary for high surge current duty. External posts
are available for adjoining commercially available heat dissipators using clamping hardware.
