DESCRIPTION
The SMP550G-FK is a Silicon P.I.N. photodiode incorporated
in a hermetic metal can package. The package window has
greater ultra-violet light transmission, thus extending the useful
spectral range of the device. The electrical terminations are via
two leads of diameter 0.018" on pitch centre diameter of 0.2". The
photodiode is electrically isolated from the package, which has a
separate earth lead.
The larger photodiode active area provides greater sensitivity
than the SMP400 range of devices, with a corresponding
reduction in speed. The photodiode structure has been optimised
for high sensitivity, light measurement applications across the
infra-red to ultra-violet spectrum. Inclusion of a suitable optical
filter into the package can produce a device that responds only to
ultra-violet light. The metal can, isolated photodiode and optional
screening mesh ensure a rugged device with a high degree of
immunity to conducted and radiated electrical interference.
