The photodiode

Webb24 feb. 2012 · The photodiode is a kind of pn junction semiconductor diode which works with the intensity of light falling on it at the reverse biased condition. Working Principle … Webb29 jan. 2024 · The diode itself acts as a capacitor with 24 pF capacitance. When you hit it with a photon, you get one electron of photocurrent, which flows through the load resistance forming a low pass filter with time constant R*24pF. You need the resistor to convert the current into a voltage.

Webb23 dec. 2024 · An equivalent circuit helps us to understand and predict the real-life functionality of an electronic component. For photodiodes, an equivalent circuit model is an essential analytical tool, because simply inserting a photodiode symbol into a schematic doesn’t tell you much about the signal that will be generated and the ways in which the … Webb11 dec. 2024 · 5. How to tell how sensitive a photodiode is? There's a curve in your device's datasheet that tells you exactly that: Combined with the line in the Characteristics table that tells you the sensitivity is 0.55 A/W at 850 nm, this gives you the sensitivity at whatever wavelength you are using. Webb20 okt. 2024 · The photodiode has an active area of approximately 1mm2. 10µW/cm2 will only put 0.1µW of light on a 1mm2 detector so the 0.06µA is about what you would expect. If the sensor was 10cm2, then you would have 100 times the current because you would have 100 times the area. The disadvantages of large area sensors include higher cost, … call jim mobile
