Series 5t: high speed red-sensitive photodiodes

This range of high-speed epitaxial photodiodes is designed specifically for low operating voltages between 3 and 5 V, making them ideal for VIS and NIR applications in conjunction with CMOS components.

Special features
  • Photodiodes with epitaxial layer structure for fast rise times at low reverse voltages.
  • Epitaxial layer thickness optimized for highest speed and maximum sensitivity at 800 nm.
  • Low operating voltage – fully depleted at 3.5 V
