UVB+UVC Photodiode – SG01XL-BC5
Extra-Large Area Broadband UV Photodiode for High-Sensitivity Industrial, Environmental, Medical, Aerospace, and Scientific Applications
The SG01XL-BC5 is a Silicon Carbide (SiC)-based broadband UV photodiode designed for precise detection across the entire UV spectrum (200–400 nm, including UVA, UVB, and UVC). With its extra-large 3.0 mm² active area, it delivers maximum photon capture and exceptionally strong photocurrents, making it ideal for low-intensity UV environments and wide-beam monitoring systems. Offering peak responsivity of 0.12 A/W, ultra-low dark current (0.5 fA), and capacitance of 250 pF, the SG01XL-BC5 ensures reliable, stable, and noise-free signals. Built on rugged SiC technology, it resists UV degradation, maintaining long-term stability in demanding conditions. The photodiode operates across a wide thermal range (−55 °C to +170 °C), ensuring durability in harsh industrial, aerospace, and environmental environments. Typical applications include sterilisation monitoring, solar radiation research, UV curing, workplace safety systems, aerospace flame detection, and photonics research. The SG01XL-BC5 combines broadband UV coverage, extra-large sensitivity, and long-term reliability for mission-critical ultraviolet monitoring.
Understanding UVB+UVC Photodiode - SG01XL-BC5
The SG01XL-BC5 is an extra-large broadband UV photodiode optimised for full-spectrum detection between 200–400 nm. Its 3.0 mm² active area maximises photon capture, producing stronger photocurrents than any smaller-area models, making it ideal for low-intensity UV detection and large-field measurement setups.
