UVC Photodiode – SG01M-C5ISO90UVC
Rugged Medium-Area UVC Photodiode with ISO90 Encapsulation for Industrial, Medical, Environmental, and Scientific Applications
The SG01M-C5ISO90UVC is a Silicon Carbide (SiC)-based UVC photodiode designed for selective detection of germicidal wavelengths in the 220–280 nm range. With a medium 0.2 mm² active area, it provides stronger photocurrents than compact detectors, making it ideal for applications requiring both sensitivity and integration flexibility. Its ISO90 encapsulation enhances mechanical strength, providing protection against dust, humidity, and mechanical stress, ensuring long-term stability in challenging environments. Featuring peak responsivity of 0.10 A/W at 265 nm, ultra-low dark current (0.1 fA), and capacitance of 20 pF, the SG01M-C5ISO90UVC delivers noise-free, fast, and reliable performance. Its visible blindness eliminates interference from IR and visible light, ensuring pure UVC-only detection. Operating across −55 °C to +170 °C, the device is built for rugged industrial, medical, aerospace, and environmental use. Applications include UVC LED monitoring, lamp validation, disinfection systems, air and water purification, workplace safety, and germicidal photonics research.
