Broadband UV Photodiode – SG01XXL-8ISO90
Ultra-Large Area UV Photodiode with ISO90 Encapsulation for High-Sensitivity Industrial, Scientific, and Aerospace Applications
The SG01XXL-8ISO90 is a Silicon Carbide (SiC) broadband UV photodiode featuring an ultra-large 7.0 mm² active area and ISO90 encapsulation, designed for maximum photon capture and rugged reliability. With a responsivity peak of 0.12 A/W at 280 nm and detection coverage across 221–358 nm, it provides accurate ultraviolet-only detection with outstanding visible blindness. Its large-area design ensures high photocurrent output, making it especially suitable for low-intensity UV monitoring, wide-beam detection, and high-sensitivity applications. ISO90 encapsulation enhances durability by protecting against dust, moisture, and environmental stress, ensuring stable long-term performance in industrial, outdoor, and aerospace environments. Featuring ultra-low dark current (0.5 fA) and capacitance of 650 pF, the SG01XXL-8ISO90 balances sensitivity with reliability. Operating between −55 °C and +170 °C, it is ideal for solar UV monitoring, sterilisation control, environmental research, photonics development, aerospace UV sensing, and industrial safety systems. It delivers high sensitivity, ruggedness, and long-term stability for mission-critical ultraviolet detection.
Understanding Broadband UV Photodiode - SG01XXL-8ISO90
The SG01XXL-8ISO90 is an ultra-large-area photodiode designed for applications where maximum UV sensitivity is essential. With a 7.0 mm² active area, it captures significantly more photons than standard detectors, delivering strong photocurrents even under low-UV intensity conditions. Its SiC construction ensures precise UV-only detection within the 221–358 nm range, peaking at 280 nm, while completely rejecting visible and infrared light. ISO90 encapsulation adds environmental resilience, protecting against contaminants, dust, and mechanical stress for outdoor and industrial use. With ultra-low dark current and wide thermal stability (−55 °C to +170 °C), the SG01XXL-8ISO90 is engineered for reliability in aerospace, industrial, and scientific environments.
