Si photodiode 8193

Product catalog summary

Overview: The Si photodiode S8193 is a high sensitivity, high reliability detector designed for X-ray monitors. It features a ceramic scintillator and offers less afterglow compared to CsI, with high X-ray sensitivity and no deliquescence.

Features: The photodiode is suitable for X-ray analysis and detection, providing 1.8 times the X-ray sensitivity of CWO. It operates effectively within a temperature range of -10 to +60 °C and can be stored between -20 to +70 °C.

Specifications: The reverse voltage is capped at 5 V. The spectral response range is from 190 to 1000 nm, with a peak sensitivity wavelength of 720 nm. Photosensitivity is measured at 0.26 A/W at 500 nm and 0.5 A/W at the peak wavelength. The dark current is between 2 to 50 pA, and terminal capacitance is 950 pF at 0 V and 10 kHz.

Performance: X-ray sensitivity is noted at 30 nA for a tube voltage of 120 keV under specified conditions. Graphs illustrate the relationship between terminal capacitance and reverse voltage, as well as dark current versus reverse voltage.

Design: The dimensional outline is provided with precise measurements, highlighting the ceramic scintillator and photosensitive surface.

Precautions and Warranty: The document includes a disclaimer and notes on product packaging. The warranty covers one year post-delivery, limited to repair or replacement for defects reported within this period. Liability is not accepted for losses due to natural disasters or improper use.

Contact Information: Contact details for Hamamatsu Photonics offices worldwide are provided for further inquiries and support.
