WebbPIN Photodiode Characteristics. Resistivity: It offers low resistivity in P , and N layers ( less than 1kΩ/cm) and high resistivity in I layer ( up to 100 kΩ/cm) Capacitance: As capacitance is inversely proportional with the gap between P and N layers, capacitance in this photodiode is lower than the standard diode. 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 …
