UVC Photodiode – SG01F-C5UVC
Compact UVC Photodiode with High Sensitivity for Medical, Industrial, Environmental, Scientific, and Safety Monitoring Applications
The SG01F-C5UVC is a Silicon Carbide (SiC)-based photodiode designed for accurate and selective detection of germicidal UVC radiation between 220–280 nm. With a compact 1.1 mm² active area, it balances high responsivity with reduced capacitance, making it ideal for integration into portable and compact monitoring systems. The device achieves peak responsivity of 0.10 A/W at 265 nm while maintaining ultra-low dark current (0.1 fA) and capacitance of 120 pF, ensuring stable, noise-free signals with rapid response times. Complete visible blindness eliminates interference from IR and visible wavelengths, ensuring pure UVC-only detection. Operating across −55 °C to +170 °C, the SG01F-C5UVC is a rugged and durable sensor suitable for demanding environments. Applications include sterilisation validation, UVC LED and lamp calibration, portable UVC exposure meters, environmental monitoring, and scientific research. Its compact form factor, fast response, and high sensitivity make it a versatile UVC photodiode solution.
