The electrical terminations are via two leads of diameter 0.005" on a pitch of 0.1". The cathode of the photodiode is electrically connected to the package. TO-18 Package Pin 1 – Anode DESCRIPTION The photodiode structure has been optimised for high sensitivity, high speed light measurement applications. The wide viewing angle provides relatively even reception over a large area. The metal can and optional screening mesh ensure a rugged device with a high degree of immunity to radiated electrical interference.
