Product Introduction
I. Characteristics of UV Photodiode SG01M-A18:
1. Made of silicon carbide (SiC) material
2. Suitable for UVA band
3. Effective detection area 0.2mm2
4. 10mW/cm2 peak irradiance generates approximately 740nA current
5. High chip stability (certified by German PTB)
II. About Silicon Carbide (SiC) Material:
SiC can withstand extreme radiation hardness, has nearly perfect visible blindness, low dark current, high-speed response, and low noise. 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 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 to provide response to UVA, UVB, and UVC bands.
III. UV Photodiode SG01M-A18 Application Areas:
Mainly used for flame control (industrial boilers), water treatment (UV intensity safety), 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 devices), UV lamp intensity testing (disinfection efficiency verification for medical devices or household disinfection cabinets), etc.
