SIC01L-C5 v 6.0 Description 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 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. Please note that this device needs an appropriate amplifier (see circuit on following page). SiC photodiodes are available as unfiltered broadband devices or with optical filters providing UV-A, UV-B, or UV-C-only sensitivity, or erythemal action curve compliance.

This requires a short circuiting of the photodiode. Usual approaches are using a Picoamperemeter or a transimpedance amplifier circuit as shown above. To make the photodiode running reliably, particularly in harsh environment, EMC compatibility and protection against dust, water, and mechanical influences is required. Below listed modules base on a SiC photodiode and guarantee this protection and safety. VTIAMO: SiC photodiodes with integrated amplifier (0-5V output), available for power intensities ranging from 1.8 pW/cm² to 18 W/cm² for UV broadband, UVA, UVB, UVC or Erythema (UV-Index) measurements. No additional amplifier needed, direct connection to voltmeter, controller, etc. UV-probe: SiC based sensor modules in customizable industry grade housings (e.g. cosine response, water pressure proof, sapphire windows) and different electronic output configurations (voltage, current, USB, Can) to choose from.
