InAs 900 – 3500 nm


The IA35 series photodiodes based on heterostructures were specially designed for operation at room temperature.

Description

The IA35 series is a spectral addition to the IG26 series of extended InGaAs photodiodes. IA35 detectors are photovoltaic, and the active area has a diameter of 500 µm.

IA35S500S4i is a high-quality yet affordable component. Compared to InAs products by traditional manufacturers of IR detectors, it offers double shunt resistance at a simultaneously quadrupled area.

Main Applications for IR Photodiodes:
  • Non-contact temperature measurement
  • Laser monitoring
  • Spectrophotometer
Key Features Include the Following:
  • Peak sensitivity: ≥1.05 A/W
  • Typical spectral range at 80% of peak sensitivity: approx. 900 nm to approx. 3500 nm
  • Shunt resistance: typically 700 ohms
