P.I.N. PHOTODIODE

DESCRIPTION

The SMP900G-JQ 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 larger photodiode active area provides greater

sensitivity than the SMP690 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 and optional screening mesh

ensure a rugged device with a high degree of immunity to

radiated electrical interference.
