Product overviewThe C30845EH is an N-type silicon PIN quadrant photodiode in a hermetically sealed TO-8 package, optimized for operation across broad near-UV to near-IR wavelengths. The large active area (50 mm², 8 mm diameter) enables reliable position sensing from both focused and defocused spots in pulsed or CW operation.
Features- Large photosensitive surface area: 50 mm²
- Low operating voltage (Vop): 45 V
- Hermetically sealed TO-8 packages
- Spectral response range: 400 to 1100 nm (designed 300 to 1100 nm)
- Very low quadrant-to-quadrant separation: 0.25 mm
Applications / NotesN-type PIN quadrant photodiode in a TO-8 hermetic package suitable for broadband, low-light-level detection and for extracting position information from focused or defocused spots in pulsed or continuous-wave systems.
