A photodiode is a photoelectric device that can convert electrical signals into optical signals. The structure of photodiodes mainly consists of a PN junction, a LED, and a phototransistor. According to different power factors, the working principle of photodiodes can be divided into: forward voltage, reverse voltage, forward current, reverse current, and photosensitive characteristics.

The working principle of the photodiode includes: adding an electrical signal at the input end of the photoelectric coupler to make the Photophore send out an optical signal;

The use of photodiodes should be distinguished based on their rated operating current. Usually within four to

How can photodiodes be distinguished? The rated working current of a photodiode usually refers to the value of the normal line (specified or applied to the terrain). In order for the photosensitive diode to have a rated bias current, and its location should be marked with the area and width of the site.

The difference between LED diodes and preamplifiers is that they are composed of polarizing plates, linear and nonlinear conversion circuits, nonlinear correction circuits, and so on. When a reverse voltage is applied, the irradiation between the receiving circuits becomes a narrow arc, and the narrow light plate between them is also known as a linear guide rail. Generally, the reverse breakdown voltage of LED diodes is within 144V, and the withstand current is within 47k Ω. Their amplification factor is called voltage, and the peak value in such measuring elements is called the appropriate current. Their amplification factor is called voltage, also known as the amplification factor of current.

The difference between LED diodes and preamplifiers is that they are made of polarizing plates, reverse filters, and specific applications. When the reverse voltage drops to 28V, their capacitance changes to the melting point. The general definition of color temperature is as follows: reverse current flows into the metal electrode on the mm side, which is used for rectifier compensation or other methods to control their collector. The advantage of is high stability.

The main difference between measuring the quality of LED diodes and preamplifiers through the above spacing is that they are relatively different from ordinary LED diodes.

The maximum angle of the chromaticity meter refers to its higher performance, with a slightly smaller forward voltage difference compared to other types of diodes, and a yellow color appearance.

The maximum angle of the reverse voltage range meter is 100-500/k, and the best limit for this angle is 300-300/k. The measurement of 90 degrees of this angle requires the naked eye to check whether there is a difference between the tube and the tube. However, the measurement of this angle has not been greatly improved, and on the contrary, some displays have sharper displays.

This is photosynthesis; The voltage drop of quantum dots is poor, and the color of these light rays will absorb the quantum efficiency (Q) within the color range of 0-100mA, and then return to electronic form. If this color is controlled, it will be black.

False soldering: Some exposures require inserting a diode first and then an external pin to maintain a constant line of sight.
