Product Introduction
I. Application fields of UV photodiode SG01D-B18:
The UV photodiode SG01D-B18 is mainly used for flame control (industrial boilers), water treatment (UV intensity insurance), UV astronomy (array detection), bullet tracking (UV cameras), ozone and pollutant monitoring, flame sensing (fire alarm safety devices, oil droplet monitoring), testing UV intensity in sunlight, and UV lamp intensity testing (disinfection efficiency verification for medical devices or household disinfection cabinets).
II. Characteristics of UV photodiode SG01D-B18:
1. Made of silicon carbide (SiC) material
2. Only for UVB band
3. Photosensitive area: 0.50mm2
4. Generates approximately 6.25nA current under 10uW/cm2 peak irradiance
5. High chip stability (certified by German PTB)
III. About silicon carbide (SiC) material:
SiC has extremely special advantages: it can withstand high-intensity radiation, is almost insensitive to visible light, has low dark current, and fast response speed. These characteristics make SiC an excellent material for making semiconductor UV detectors that can suppress visible light. SiC detectors can operate at temperatures up to 170°C for long periods, have a low temperature coefficient (<0.1%/K), and low noise, enabling effective monitoring of very low radiation intensities (with appropriate amplifiers).
