DESCRIPTION
The SMP400G is a Silicon P.I.N. photodiode specifically
designed for optical fibre communication. The device is
incorporated in a compact, low profile, hermetic metal can
package.
A glass bead lens incorporated into the TO-46 case
provides an efficient optical design. This affords substantial
mis-alignment between the device and a fibre optic cable
without degrading the coupling efficiency.
The electrical terminations are via three leads of
diameter 0.02" on a pitch of 0.1". Both cathode and anode
connections to the photodiode are electrically isolated from
the package.
