SG01D-A18ISO90 SiC UVA-only Photodiode
The SG01D-A18ISO90 is a SiC UVA-only photodiode, with two isolated pins and one additional grounded pin, that 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 detectors.
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.
