UVC Photodiode – SG01S-C18UVC
Compact UVC Photodiode for Reliable Industrial, Environmental, Medical, and Scientific Germicidal Monitoring Applications
The SG01S-C18UVC is a compact Silicon Carbide (SiC)-based photodiode designed specifically for selective UVC detection in the wavelength range of 220–280 nm. With a 0.06 mm² active area, it is optimised for applications requiring highly accurate, space-efficient UV detection. The device features peak responsivity of 0.1 A/W at 265 nm, delivering excellent sensitivity for germicidal monitoring, sterilisation systems, and disinfection validation. Engineered with ultra-low dark current (0.1 fA) and capacitance of 15 pF, the SG01S-C18UVC ensures noise-free operation and rapid response times for real-time monitoring tasks. Its inherent visible blindness completely eliminates interference from visible and infrared light, ensuring pure UVC-only measurements. Operating across a broad thermal range (−55 °C to +170 °C), the device provides stable, long-term performance in demanding environments. Typical applications include UVC lamp monitoring, sterilisation systems, water purification validation, environmental studies, and scientific research. The SG01S-C18UVC combines compact design, UVC selectivity, and long-term reliability.
