High-Speed Circular Photodiode for Electron Detection | AXUV63HS1

We are now supplying a family of new High-Speed Circular Photodiode. These photodiodes, will idealy be used for Electron Detection. The AXUV-family detectors features high-performance measurement of photons, electrons, or X-rays from 0.0124 nm to 190 nm and will detect energy from 100 eV to 50 keV.

The lead soldering temperature is 260°C and to protect the wirebond and photodiode chip the detector is shipped with a cover plate. For storage and operating temperatures ideal range is from  -10°C to +40°C (ambient). The Photodiode will also be suitable for vaacum or nitrogen environments, but then in a range from -20°C to +80°C.


  • Circular active area: 9 mm2 (typically 63 mm2)
  • Rise time: 10 nsec
  • Maximum dark current: 100 nA
  • Minimum reverse breakdown voltage: 160 Volts
  • For additional specifications and responsivity graphs, download the datasheet.
