Integrated optical filters included in SiC UV Photodiodes
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.
