Broadband UV Photodiode – SG01XL-5ISO90
Extra-Large Area UV Photodiode with ISO90 Encapsulation for Rugged, High-Sensitivity Industrial and Scientific Applications
The SG01XL-5ISO90 is a Silicon Carbide (SiC) broadband UV photodiode with an extra-large 3.0 mm² active area and ISO90 encapsulation, designed for applications requiring maximum sensitivity and environmental ruggedness. With a responsivity peak of 0.13 A/W at 280 nm and detection coverage between 221–358 nm, it provides highly accurate UV-only detection with complete visible blindness. The large active area ensures stronger signal output and improved photon capture, making it ideal for low-intensity UV monitoring and wide-beam applications. ISO90 encapsulation offers added protection against moisture, dust, and mechanical stress, ensuring long-term stability even in harsh industrial and outdoor environments. With an ultra-low dark current of 0.1 fA and capacitance of 250 pF, the SG01XL-5ISO90 balances high sensitivity with stable operation. Operating from −55 °C to +170 °C, it is well suited for solar UV monitoring, sterilisation validation, flame detection, aerospace UV sensing, and photonics research.
Understanding Broadband UV Photodiode - SG01XL-5ISO90
The SG01XL-5ISO90 combines an extra-large 3.0 mm² active area with ISO90 encapsulation, making it one of the most sensitive and rugged UV photodiodes available. Its Silicon Carbide-based construction ensures accurate UV-only detection across 221–358 nm, with a responsivity peak of 0.13 A/W at 280 nm, while completely rejecting visible and infrared wavelengths. The large area increases photon capture, boosting signal currents in wide-beam or low-intensity UV environments. ISO90 encapsulation provides added durability against contaminants, mechanical stress, and environmental degradation, ensuring stable long-term operation. With ultra-low dark current and reliable performance between −55 °C and +170 °C, it is ideal for critical industrial, aerospace, and research applications.
