Silicon carbide (SiC) UV photodiodes for ultraviolet radiation detection introduced by Advanced Photonix

July 17, 2023
Devices are for tasks that require visible wavelength blocking while operating at high temperatures, and response between 200 and 400 nanometers.

CAMARILLO, Calif. – Advanced Photonix Inc. in Camarillo, Calif., is introducing two silicon carbide (SiC) broadband UV photodiodes for ultraviolet source monitoring in ultraviolet (UV) index monitoring, dose measurement, and flame detection applications.

The APX-SC0010 features a 1 square millimeter active area, and the APX-SC00025 features an active area of 0.25 square millimeters. The solar-blind devices operate in the spectral range from 200 to 380 nanometers and can block out any wavelengths outside this range, including those in the visible spectrum.

The UV photodiodes have a broadband (UVA+UVB+UVC) sensitivity peaking at 275 nanometers, UV responsivity characteristics, and low dark current even at elevated temperatures.

These devices are for ultraviolet radiation detection tasks that require outstanding visible wavelength blocking. They can operate at high temperatures, are responsive between 200 and 400 nanometers, and are not responsive to longer wavelengths because of the wide bandgap.
