UVC Photodiode – SG01S-C5UVC
Compact UVC Photodiode for Precision Industrial, Medical, Environmental, and Scientific Sterilisation and Monitoring Applications
The SG01S-C5UVC is a compact Silicon Carbide (SiC)-based photodiode designed for accurate detection of germicidal UVC radiation in the 220–280 nm range. With a small 0.06 mm² active area, it is optimised for portable devices, embedded systems, and space-limited applications requiring high accuracy. Delivering peak responsivity of 0.10 A/W at 265 nm, the SG01S-C5UVC ensures precise detection in disinfection and sterilisation systems. It features ultra-low dark current (0.1 fA) and capacitance of 15 pF, providing noise-free signals and rapid responsiveness for real-time UVC monitoring. Built with SiC technology, it achieves complete visible blindness, eliminating interference from visible and infrared light for pure UVC detection. Designed for rugged applications, the device operates reliably from −55 °C to +170 °C, ensuring long-term stability in medical, industrial, environmental, and scientific setups. Applications include UVC LED monitoring, lamp validation, sterilisation control, and water/air purification systems.
