The electrical terminations are via three leads of diameter 0.008" on a pitch centre diameter of 0.1". The photodiode is electrically isolated from the package, which has a separate earth lead. The photodiode structure has been optimised for high sensitivity, high speed light measurement applications acrosss 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, isolated photodiode and optional screening mesh ensure a rugged device with a high degree of immunity to conducted and radiated electrical interference. 2 1 TO-18 Package Pin 1 – Anode Pin 2 – Cathode Pin 3 –Case ABSOLUTE MAXIMUM RATINGS (Tcase = 25°C unless otherwise stated) Operating temperature range Storage temperature range Temperature coefficient of responsively Temperature coefficient of dark current Reverse breakdown voltage Semelab plc.
