Sic UV Photodiodes of Broadband Type

1.Properties of the SG01S–18 UV photodiode

Broadband UVA+UVB+UVC, PTB reported high chip stability

Active Area A = 0,06 mm2

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

10mW/cm2 peak radiation results a current of approx. 780 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 coefficient 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 amplifier (see typical circuit on page 3).

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 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).
