  • Manufacturer Part No VTB8441BH

Product Overview

The VTB8441BH is a blue enhanced Silicon Photodiode on 8mm ceramic substrate coated with IR blocking filter having a 5.2mm² active area designed for spectral response between 330 and 720nm. This series of P on N Silicon planar photodiode has been designed for optimum response through the visible part of the spectrum. This photodiode is primarily intended to be used in photovoltaic mode but may be used with a small reverse bias. It also been designed to exhibit very high shunt resistance, a characteristic which leads to low offsets when used in high gain trans-impedance op-amp circuits.
  • UV to IR spectral range
  • Integral IR blocking filter
  • 920nm Peak wavelength
  • Medium size active area
  • 1 to 2% Linearity over 7 to 9 decades
  • Very low dark current
  • Very high shunt resistance

This part looks like a reasonable priced photodiode for use in the visible since it has a good blue response and has a IR reject filter. Would like to know what the spectral response curve looks like. The data sheet provides the spectral response range as 330-720 nm, with a peak at 580 nm, but a curve would be nice to ensure that there are no surprises.

Thanks in advance.

As you requested, you will find attached the spectral response curve for the VTB8441BH. The spectral response can be found on image(VTB PD2.jpg-graph on the lower right corner).

Is it possible to know the application in which you intend to use that part? I just want to make sure we recommend the best part for the application.
