The G8931-20 is an InGaAs avalanche photodiode designed for distance measurement, optical communication, and low-light-level detection, featuring a 0.2 mm diameter photosensitive area and housed in a TO-18 package with a borosilicate glass window AR-coated for 1.55 µm. It operates with a spectral response range of 0.95 to 1.7 µm, peaking at 1.55 µm, and provides a typical gain of 30 at 1 µA photocurrent. The device has a breakdown voltage range of 40 to 60 V, a terminal capacitance of up to 2 pF at 90% of breakdown voltage, and a dark current of up to 200 nA at 90% of breakdown voltage. Its operating temperature range is -40 to +85 °C, with a storage temperature range of -55 to +125 °C. The breakdown voltage has a temperature coefficient of 0.11 V/°C.
