UVB+UVC Photodiode – SG01M-BC5
Medium-Area Broadband UV Photodiode for Industrial, Medical, Environmental, Aerospace, and Scientific Monitoring Applications
The SG01M-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 its medium 0.2 mm² active area, it balances integration flexibility with enhanced sensitivity, providing stronger photocurrents compared to small-area detectors. Its broadband responsivity ensures accurate UV monitoring while maintaining complete visible blindness, guaranteeing precise ultraviolet-only detection. With a peak responsivity of 0.12 A/W, ultra-low dark current (0.1 fA), and capacitance of 10 pF, the SG01M-BC5 delivers clean, noise-free signals and rapid response times. Built on robust SiC technology, it resists UV degradation, ensuring long-term stability and reliability. Capable of operating across −55 °C to +170 °C, the SG01M-BC5 is suitable for harsh environments and demanding applications. Typical uses include UV curing systems, sterilisation monitoring, flame detection, solar radiation research, workplace safety, and advanced photonics studies.
