Working Principle

The PDB-C168 photodiode works by converting incident light energy to a current, which is then amplified by an external current amplifier. The external current amplifier is responsible for masking off any fluctuations in current due to environmental changes, or any variations in photon flux.In essence, a typical optical detecter circuit consists of a reverse biased photodiode, a load resistor, an output resistor, and an operational amplifier (Op-Amp). The operating principle of the photodiode is based on the fact that as current is increased when light is incident on it, causing the voltage across the diode to drop which is measured by the amplifier. The output of the amplifier is then measured to determine the incident optical radiation power corresponding to the light signal incident on the detector.The photodiode PDB-C168 provides a good linear response over a wide wavelength range, and has a wide spectral response from 400nm to 900nm. This makes it an ideal choice for applications that require high speed performance and low dark current. The photodiode also has a low reverse bias leakage current, making it suitable for applications which require a low noise level.
