UVC Photodiode – SG01D-C5ISO90UVC
Large-Area Rugged UVC Photodiode with ISO90 Encapsulation for Industrial, Medical, Aerospace, and Scientific Applications
The SG01D-C5ISO90UVC is a Silicon Carbide (SiC)-based photodiode optimised for the detection of germicidal UVC radiation in the 220–280 nm range. With a large 2.0 mm² active area, it delivers strong photocurrents, ensuring high sensitivity for demanding applications such as sterilisation monitoring, UVC LED validation, and lamp calibration. Encased in ISO90 rugged encapsulation, the device is protected against dust, moisture, and mechanical stress, guaranteeing reliable operation in harsh industrial and outdoor environments. Featuring peak responsivity of 0.10 A/W at 265 nm, ultra-low dark current (0.1 fA), and 200 pF capacitance, the SG01D-C5ISO90UVC ensures stable, noise-free signals with fast responsiveness. Its complete visible blindness eliminates interference from visible and IR light, allowing pure UVC-only detection. Designed for long-term stability, it performs reliably across −55 °C to +170 °C, making it suitable for aerospace, medical, and scientific systems requiring durable UVC monitoring.
