UVC Photodiode – SG01M-C18ISO90UVC
Medium-Area Rugged UVC Photodiode with ISO90 Encapsulation for Industrial, Medical, Aerospace, and Scientific Applications
The SG01M-C18ISO90UVC is a Silicon Carbide (SiC)-based photodiode designed for precise detection of germicidal UVC radiation in the 220–280 nm range. Featuring a medium 0.2 mm² active area, it offers enhanced sensitivity and stronger photocurrents than compact models while maintaining easy integration. ISO90 encapsulation provides superior mechanical robustness and environmental resistance, protecting the device against dust, moisture, and stress for long-term stability. With peak responsivity of 0.10 A/W at 265 nm, ultra-low dark current (0.1 fA), and capacitance of 20 pF, it ensures noise-free signals and fast responsiveness for real-time UVC monitoring. Complete visible blindness eliminates interference from visible and IR radiation, ensuring pure UVC-only detection. Operating reliably from −55 °C to +170 °C, the SG01M-C18ISO90UVC is suited for demanding environments such as aerospace, defence, healthcare, and industrial sterilisation systems. Applications include UVC LED monitoring, lamp calibration, disinfection validation, air and water purification, and scientific photonics research.
