DESCRIPTION
Cathode
and case
Anode
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
miss-alignment between the device and a fibre optic cable
without degrading the coupling efficiency.
TO-18 Package
Pin 1 – Anode
Pin 2 – Cathode & Case
The electrical terminations are via two leads of diameter
0.02" on a pitch of 0.1". The cathode and case connections
are electrically connected.
