An alternative to blue enhanced Si PIN diodes is offerred from SiC, since they are naturally ‘blind’ in the deep UV and visible, offering a good response between 200nm and 400nm. SiC is also more resistant to damage when exposed to harsh UV radiation compared to Si photodiodes.

Available in small TO-18 packages, a 0.1mm2 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 and +125˚C.

These SiC photodiodes are suitable for harsh environments, such as UV sterilisation, sun light and space applications, as well as being excellent companions for UV instruments and flame control.
