Si APD S14645 series - 1

Si APD S14645 series High speed, compact Si APD for LiDAR (900 nm band) featuring low-bias operation This Si APD is suitable for detecting light in the 900 nm band, which is increasingly used in optical rangefinders. With the same shape as the previous product (S12926 series), this Si APD features less variation in breakdown voltage, reduced dark current, and expanded storage and operating temperatures. Optical rangefinders Peak sensitivity wavelength: 840 nm (M=100) Low bias operation: Breakdown voltage=195 V max. H igh-speed response: Cutoff frequency=600 MHz typ. (λ=900 nm, M=100) Reduction of breakdown voltage variation: 175 ± 20 V Structure Parameter Photosensitive area size*1 Effective photosensitive area Package Plastic (silicone resin) *1: Photosensitive area in which a typical gain can be obtained Absolute maximum ratings Parameter Operating temperature*2 Storage temperature*2 Reverse current (DC) Forward current Soldering temperature Symbol Topr Tstg IR max IF max Tsol When there is a temperature difference between a product and the surrounding area in high humidity environments, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability. *3: Reflow soldering, JEDEC J-STD-020 MSL 2a, see P.4 Note: xceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the E product within the absolute maximum ratings.
