1.General Features:
Properties of the SG01D-C18 UV photodiode

• UVC-only sensitivity, compliant with DVGW W294, PTB reported high chip stability

• Active Area A = 0,50 mm2

• TO18 hermetically sealed metal housing, 1 isolated pin and 1 case pin

• 10µW/cm2 peak radiation results a current of approx. 6 nA



2.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 UV de-

tectors. The SiC detectors can be permanently operated at up to 170°C (338°F). The temperature coeffcient of signal

(responsivity) is also low, < 0,1%/K. Because of the low noise (dark current in the fA range), very low UV radiation

intensities can be measured reliably. Please note that this device needs an appropriate amplifer (see typical 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 fltered versions lead to a tighter sensitivity range. All photodiodes have a hermeti-

cally sealed metal housing (TO type), either a 5,5 mm diameter TO18 housing or a 9,2 mm TO5 housing. Further op-

tion is either a 2 pin header (1 isolated, 1 grounded) or a 3 pin header (2 isolated, 1 grounded).
