YAG-444 Series Photodiodes - Si PIN - 11.3 mm

Excelitas Technologies’ YAG series of Silicon PIN detectors are high-performance N-type or P-type Si PIN photodiodes in hermetically sealed TO packages.

These photodiodes perform well over the 400 nm to 1100 nm wavelength range, with enhanced IR responsivity, making them ideal for 1064 nm detection applications.

A guard ring collects current generated outside the active area, ensuring the current will not contribute to noise.

Because of its large active area, the device is useful in obtaining position information from both focused and defocused spots in either pulsed or CW mode.

Key Features and Benefits:

  • High quantum efficiency at 1064 nm
  • Package style: Hermetic TO-5 can
  • Available in N- and P-type configuration
  • Active diameter (mm): 11.3
