Product Introduction
I. Features of UV Photodiode SG01XL Series:
1. Made of silicon carbide (SiC) material
2. Broadband (UVA+UVB+UVC)
3. Active area 7.6mm2
4. 10uW/cm2 peak irradiance generates approximately 99nA current
5. High chip stability (certified by German PTB)
II. About Silicon Carbide Material (SiC)）：
SiC can withstand extreme radiation hardness, nearly visible-blind, low dark current, high-speed response, and low noise special properties; these features make SiC an excellent material for visible-blind UV detectors. SiC detectors can operate at temperatures up to 170°C, and the temperature coefficient of the signal (responsivity) is also very low, <0.1%/K. Due to low noise (dark current at fA level), very low UV radiation intensities can be reliably measured (with appropriate amplifiers).
SiC photodiodes can be used as unfiltered broadband detection devices or with optical filters, providing response to UVA, UVB, and UVC bands.
III. Application Fields of UV Photodiode SG01XL Series:
Mainly used for flame control (industrial boilers), water treatment (UV intensity insurance), UV astronomy (array detection), projectile tracking (UV cameras), ozone and pollutant monitoring, flame sensing (fire alarm safety devices, oil droplet monitoring), testing UV intensity in sunlight (gifts, cosmetic tools), UV lamp intensity testing (disinfection efficiency inspection of medical devices or household disinfection cabinets), etc.
