The G12430-046D is a 46-element one-dimensional InGaAs PIN photodiode array in a 48-pin ceramic DIP package, designed for near-infrared spectroscopic analysis. Each element has a photosensitive area of 0.2 mm × 1 mm with a pitch of 0.25 mm. The device operates from -20 to +70 °C and withstands a maximum reverse voltage of 5 V. It exhibits peak sensitivity at 1.55 µm with a photosensitivity of 0.95 A/W(typical), a dark current of 250 pA (typical) at VR=1 V, and a cutoff frequency of 60 MHz (typical). Terminal capacitance is 35 pF (typical) at 1 MHz. The window is made of borosilicate glass with resin sealing and no AR coating. Pinout supports individual channel readout via operational amplifiers.
