High Speed PIN Photodiode Offers Enhanced Sensitivity for Visible Light

vemd8080VEMD8080  Delivers Precise Signal Detection in 4.8 mm by 2.5 mm SMD Package with Industry-Low 0.48 mm Profile
  • Featuring fast switching times and low capacitance of 47 pF for precise signal detection in wearable devices and medical applications.
  • 0.37 mm lower profile than competing solutions
  • Utilizes Vishay’s proven wafer technology to detect visible and near infrared radiation
  • For green LEDs, sensitivity represents a 30 % improvement over the standard technology in previous-generation solutions
  • Small size and high sensitivity enable slim sensor designs for optical heart rate detection in wearable devices such as fitness trackers and smart watches
  • The VEMD8080’s rectangular shape allows several light emitting diodes to be placed close to the radiant sensitive area to maximize the signal
