The electrical terminations are via three leads of diameter 0.008" on a pitch centre diameter of 0.1". The taller can structure affords a greater range of optical filter options. The photodiode is electrically isolated from the package, which has a separate earth lead. 3 2 1 TO-18 Package Pin 1 – Anode EXCELLENT LINEARITY LOW NOISE PHOTODIODE ISOLATED FROM PACKAGE WIDE SPECTRAL RESPONSE WIDE INTRINSIC BANDWIDTH LOW LEAKAGE CURRENT LOW CAPACITANCE INTEGRAL OPTICAL FILTER OPTION note 1 TO18 HERMETIC METAL CAN PACKAGE EMI SCREENING MESH AVAILABLE Pin 2 – Cathode Pin 3 – Case The photodiode structure has been optimised for high sensitivity, high speed light measurement applications. The moderate viewing angle facilitates easy alignment of the device with on-axis illumination sources. 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.
