SiC offers an excellent alternative to blue enhanced Si PIN diodes since they are naturally ‘blind’ in the deep UV and visible, offering a good response between 200 nm and 400 nm. SiC is also significantly more resistant to damage when exposed to harsh UV radiation compared to Si photodiodes.
Available in small TO-18 packages, a 0.1 mm² active chip provide simple measurement of incident radiation. Optional integrated UV-A, UV-B and UV-C optical filters in TO-5 packages are available. Custom filters can also be installed. Isolated leads are available as well as low and high operating temperatures between -40˚C and +125˚C.
These SiC photodiodes are ideal for harsh environments, such as UV sterilisation, sun light and space applications, as well as being excellent companions for UV instruments and flame control.
