InGaAs APD that greatly reduces dark current This InGaAs APD (avalanche photodiode) greatly reduces dark current over existing products by the use of a new device structure and improved processing. The G14858-0020AA is used for distance measurement, low-light-level detection, and so on. Distance measurement Low-light-level detection High sensitivity Structure Parameter Window material Package Photosensitive area Specification Borosilicate glass (AR coated: 1.55 µm) TO-18 ɸ0.2 Absolute maximum ratings Parameter Reverse current Forward current Operating temperature*1 Storage temperature*1 Symbol IR max IF max Topr Tstg *1: No dew condensation Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings. Electrical and optical characteristics (Ta=25 °C) Parameter Symbol Condition Min. Typ. Max.
