Surface mount type short wavelength APD has been released

Si APD S17268 series

  • Hamamatsu Photonics K.K. Solid State Division

The S17268 series is surface mount type Si APD with high sensitivity in the short wavelength range. While maintaining performance equivalent to conventional TO-18 package products, it achieves more compact size and lower cost. With a high quantum efficiency of 82 % at 450 nm, it also enables low-noise and low-bias operation. With a compact size of 1.8 × 2.0 × 0.9 mm, it is suitable for integration into space-constrained devices such as optical rangefinders, industrial LiDAR, and flow cytometers. Two types with different photosensitive areas are available.

Features

  • Compact, surface mount type package
  • High short-wavelength sensitivity
  • Low bias operation: Breakdown voltage=160 V typ.
  • Low noise
  • High-speed response: Cutoff frequency=2 GHz typ.
