The S8559 is a silicon photodiode integrated with a CsI(Tl) scintillator for X-ray detection below 100 keV, housed in a package with a photosensitive surface measuring 9.7 mm × 9.8 mm and a lead anode terminal marked for polarity. It operates from -10 °C to +60 °C and withstands a maximum reverse voltage of 5 V. The spectral response ranges from 190 to 1000 nm, with a peak sensitivity at 720 nm. At 500 nm, the photo sensitivity is 0.26 A/W, and the dark current is up to 50 pA at 10 mV reverse voltage. Terminal capacitance is 950 pF at 0 V and 10 kHz. X-ray sensitivity is 52 nA at 120 kV tube voltage with a 6 mm aluminum filter. The CsI scintillator requires avoidance of high humidity due to deliquescence.
