A
thyristor is a solid-state semiconductor device with four
layers of alternating N and P-type material. They act as bistable
switches, conducting when their gate receives a current pulse, and
continue to conduct while they are forward biased (that is, while
the voltage across the device is not reversed).
An SCR consists of four layers of alternating P and N type
semiconductor materials. Silicon is used as the intrinsic
semiconductor, to which the proper dopants are added. The junctions
are either diffused or alloyed. The planar construction is used for
low power SCRs (and all the junctions are diffused). The mesa type
construction is used for high power SCRs. In this case, junction J2
is obtained by the diffusion method and then the outer two layers
are alloyed to it, since the PNPN pellet is required to handle
large currents. It is properly braced with tungsten or molybdenum
plates to provide greater mechanical strength. One of these plates
is hard soldered to a copper stud, which is threaded for attachment
of heat sink. The doping of PNPN will depend on the application of
SCR, since its characteristics are similar to those of the
thyratron. Today, the term thyristor applies to the larger family
of multilayer devices that exhibit bistable state-change behaviour,
that is, switching either ON or OFF.
