High speed, compact Si APD for LiDAR (800 nm band) featuring low-bias operation The S14644 series is a compact, surface mount type Si APD that achieves high sensitivity in the 800 nm band. This is suitable for laser monitoring of optical rangefinders widely used from consumer electronics to industrial use. Optical rangefinders Peak sensitivity wavelength: 800 nm (M=100) Low-bias operation: Breakdown voltage=180 V max. H igh-speed response: Cutoff frequency=1 GHz typ. (λ=800 nm, M=100) Reduction of breakdown voltage variation 160 ± 20 V Structure Parameter Photosensitive area*1 Effective photosensitive area Package Glass epoxy (silicone resin) *1: Photosensitive area in which a typical gain can be obtained Absolute maximum ratings Parameter Reverse current (DC) Forward current Operating temperature*2 Storage temperature*2 Soldering temperature Symbol IR max IF max Topr Tstg 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.5 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.
