1/4General Features

Properties of the SG01D–5LENS UV photodiode• Broadband UVA+UVB+UVC, PTB reported high chip stability, for flame detection• Radiation sensitive area A = 0.5 mm2• TO5 hermetically sealed metal housing with concentrator lens, 1 isolated pin and 1 case pin• 10µW/cm2 peak radiation results a current of approx. 350 nA
About the material Silicon Carbide (SiC)
SiC provides the unique property of extreme radiation hardness, near-perfect visible blindness, low dark current,high speed and low noise. These features make SiC the best available material for visible blind semiconductor UVdetectors. The SiC detectors can be permanently operated at up to 170°C (338°F). The temperature coefficient ofsignal (responsivity) is also low, < 0.1%/K. Because of the low noise (dark current in the fA range), very low UVradiation intensities can be measured reliably. Please note that this device needs an appropriate amplifier (seetypical circuit on page 3).
Options
SiC photodiodes are available with seven different active chip areas from 0.06 mm2 up to 36 mm2. Standard
version is broadband UVA-UVB-UVC. Four filtered versions lead to a tighter sensitivity range. All photodiodes havea hermetically sealed metal housing (TO type), either a 5.5 mm diameter TO18 housing or a 9.2 mm TO5 housing.
Further option is either a 2 pin header (1 isolated, 1 grounded) or a 3 pin header (2 isolated, 1 grounded).

Application Note for Photodiodes
For correct reading of the photodiode the current (and NOT the voltage) must be analyzed. This requires a shortcircuiting of the photodiode. Usual approaches are using a Picoamperemeter or a transimpedance amplifier circuit
as shown on page 3.
