Description
The SMP devices are a range of single element Silicon
P.I.N. photodiodes. The device structure has be designed
to give maximum sensitivity and high speed of response.
The device structure shown above has a high resistance
intrinsic layer sandwiched between P and N+ layers.
Various optical filters can be incorporated inside the
package to pass selected regions of the ultra-violet to
infra-red spectrum. The optical filters can be ionically
coloured glass or vapour-deposited dielectric layers on a
glass substrate. For more details of the filter permutations,
contact Semelab Plc.

Note:
The photodiodes are operated at zero bias for best sensitivity. Operation at reverse bias will enhance further the speed
of response. Typical circuits for these configurations are show below.
