SiC UV detectors are used, for example, to monitor UV lamps in the sterilization of water and curing, to monitor flames in the UV, or to measure the effect of solar or UV lamp radiation on the skin – erythema weighting.
They feature a very low dark current level in the fA range, extreme temperature stability (ΔT < ‑0.06%/K), and high operating temperatures of up to +150°C. SiC is solar blind. The spectral sensitivity of 200-400 nm can be adjusted to UV-A, UV-B, or UV-C by integrating special radiation-proof filters.
The long-term stability is excellent even at high UV-C radiation doses of up to 1000 W/cm2. The photodiodes are also available with an integrated amplifier.
Contrary to recent reports in the technical press claiming the opposite, there have not been any shortages in the supply with silicon carbide.
