Detection Technology, Inc. | Piisilta 1, 91100 Ii, FINLAND | Tel. +358 8 553 6600 | Fax +358 8 553 6611 | http://www.deetee.com | contact@deetee.com PDC and XRB series High performance diodes DS0000042A Detection Technology offers a selection of high performance PIN photodiodes which are optimized for various kinds of light and ionizing radiation measurements. Depending on your application, the best possible diode may be selected from our standard series of photodiodes. Each photodiode series has its own unique manufacturing process and specially selected raw silicon wafer material to ensure the best electrical and optical characteristics matching with your application and its requirements. PDC Series PDC-series photodiodes are extra high-resistivity PIN photodiodes with an excellent spectral response at 550 nm. This is achieved by using ultra pure starting material, special high-purity manufacturing process, and optimized optical filtering. PDC-series photodiodes also incorporate a unique guard-ring structure, which greatly reduces leakage current in biased operation. Benefits x Fast response time x High sensitivity x Extremely low noise due to - ultra-low capacitance - low leakage current Typical applications x Scintillator applications (e.g. CsI(Tl), CdWO4, GOS, plastic scintillators) x High-speed pulse counting XRB Series XRB-series high-resistivity diodes are optimized for ionizing radiation detection. Excellent performance is based on the use of a high-resistivity silicon starting material and a high-purity manufacturing process. High radiation tolerance and depressed light sensitivity are achieved by the use of a specially developed radiation entrance window processing. Benefits x Excellent charge collection efficiency due to high-purity processing x Stable operation in harsh radiation environment x Depressed light sensitivity Typical applications x X-ray dose and quality measurements x X-ray spectroscopy x Beta intensity and spectroscopy x high energy physics and synchrotron research X-ray effiency vs. energy in XRB series diodes Effiency (%) Energy (keV) 0,1 1,0 10,0 10 100 1000 100,0 Spectral response in PDC series 200 Spectral response (A / W) Wavelength (nm) 0,0 0,1 0,2 0,3 0,4 0,5 0,6 0,7 280 360 440 520 600 680 760 840 920 1000 CR Cross section of PDC and XRB Depletion region Guard ring Active area SIO2 Light (PDC) / Radiation (XRB) n+ Implant High-purity n-type substrate 2 2 3 1 1) Optimized optical window (PDC) Special radiation hard window (XRB) 2) p+ implant 3) Aluminum metallization X-ray transmission through XRB series diode’s entrance window Transmission (%) X-ray energy (eV) 20 40 60 80 100 0 1000 2000 3000 4000 5000
