The S8193 is a silicon photodiode designed for X-ray detection with a ceramic scintillator. It has a package size of 10.1 mm × 9.8 mm × 1.3 mm with a photosensitive surface area of 9.2 mm × 7.4 mm. The device operates within a temperature range of -10 °C to +60 °C and withstands a maximum reverse voltage of 5 V. Its peak spectral sensitivity is at 720 nm with a photosensitivity of 0.5 A/W at that wavelength and 0.26 A/W at 500 nm. Dark current is up to 50 pA at 10 mV reverse bias, and terminal capacitance is 950 pF at 0 V and 10 kHz. X-ray sensitivity is 30 nA under 120 keV conditions. Afterglow is less than 0.1% after 3 ms and less than 0.01% after 30 ms, and it exhibits no deliquescence unlike cesium iodide.
