UVB+UVC Photodiode – SG01L-BC5
Large-Area Broadband UV Photodiode for Industrial, Medical, Environmental, Aerospace, and Scientific Monitoring Applications
The SG01L-BC5 is a Silicon Carbide (SiC)-based broadband UV photodiode designed for accurate detection across the full UV spectrum (200–400 nm, including UVA, UVB, and UVC). With a large 0.8 mm² active area, it provides enhanced sensitivity and strong photocurrents, making it highly effective in low-intensity or wide-beam UV detection applications. Offering peak responsivity of 0.12 A/W, ultra-low dark current (0.2 fA), and capacitance of 40 pF, the SG01L-BC5 ensures stable, noise-free, and rapid performance. Its inherent visible blindness eliminates interference from visible and infrared light, ensuring pure UV detection. Built for rugged environments, it operates reliably from −55 °C to +170 °C, providing long-term stability in demanding industrial, environmental, aerospace, and research conditions. Typical applications include UV curing, sterilisation validation, flame detection, solar UV studies, workplace safety, and advanced photonics research. The SG01L-BC5 offers broadband coverage, large-area sensitivity, and reliable durability for mission-critical UV monitoring.
Understanding UVB+UVC Photodiode - SG01L-BC5
