UVA Photodiode – SG01L-A5UVA
Large-Area UVA Photodiode for Precision Industrial, Medical, Environmental, Aerospace, and Scientific Monitoring Applications
The SG01L-A5UVA is a Silicon Carbide (SiC)-based photodiode optimised for selective UVA detection across 315–400 nm, delivering accurate and interference-free ultraviolet monitoring. With a peak responsivity of 0.12 A/W at 330 nm, it ensures precise UVA-only measurements without influence from UVB, UVC, visible, or IR radiation. Featuring a 0.8 mm² active area, the SG01L-A5UVA offers enhanced photon capture and strong photocurrent output, making it suitable for applications requiring higher sensitivity. Its ultra-low dark current of 0.2 fA and capacitance of 40 pF provide noise-free performance with rapid response times, even under low-intensity UVA conditions. Built to withstand harsh environments, the photodiode operates reliably across −55 °C to +170 °C, ensuring stability and durability. Applications include UVA curing, sterilisation monitoring, solar radiation research, aerospace UV sensing, workplace safety systems, and photonics R&D. The SG01L-A5UVA combines large-area sensitivity, durability, and UVA selectivity for mission-critical ultraviolet monitoring.
Understanding UVA Photodiode - SG01L-A5UVA
The SG01L-A5UVA is a large-area photodiode engineered for high-sensitivity UVA detection in the 315–400 nm range, with peak responsivity at 330 nm.
