DESCRIPTION
The SMP525G-EK 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 of 0.2". The cathode of the photodiode is
electrically connected to the package.
The photodiode active area provides asymmetric viewing
angles in two orthogonal directions. The photodiode
structure has been optimised for high sensitivity,
asymmetric 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 and
optional screening mesh ensure a rugged device with a
high degree of immunity to radiated electrical interference.
