UVA Photodiode – SG01M-A5UVA
Medium-Area UVA Photodiode for Reliable Industrial, Environmental, Medical, and Research Ultraviolet Monitoring Applications
The SG01M-A5UVA is a Silicon Carbide (SiC) photodiode specifically designed for selective UVA detection, delivering precision across the 315–400 nm range with a peak responsivity of 0.12 A/W at 330 nm. Featuring a medium-sized 0.2 mm² active area, the SG01M-A5UVA provides a balance between compact integration and high sensitivity, making it ideal for industrial, research, and portable UVA monitoring systems. With ultra-low dark current (0.1 fA) and capacitance of 10 pF, it ensures noise-free performance and fast response times for real-time UVA measurements. The device operates reliably across extreme temperatures (−55 °C to +170 °C), ensuring long-term stability in demanding applications such as sterilisation monitoring, UVA curing, phototherapy calibration, solar UV studies, and aerospace UV sensing. By combining medium-area sensitivity, rugged durability, and UVA-only selectivity, the SG01M-A5UVA is an essential solution for industries requiring precise UVA monitoring.
Understanding UVA Photodiode - SG01M-A5UVA
The SG01M-A5UVA is a medium-area UVA photodiode built on Silicon Carbide technology to ensure highly selective UVA detection. Covering the 315–400 nm range with a responsivity peak of 0.12 A/W at 330 nm, it provides precise UVA-only measurements without interference from UVB, UVC, visible, or IR radiation. Its 0.2 mm² active area offers improved sensitivity over compact detectors while remaining integration-friendly for industrial, laboratory, and portable systems. With ultra-low dark current (0.1 fA) and capacitance of 10 pF, it ensures high signal-to-noise ratio and rapid response. Designed for reliability, it operates between −55 °C and +170 °C.
