Photodiodes (results: 86)

Photodiodes and their usage

Diodes are being used for various purposes. Usually they represent an operation of a certain function, however it is not their only application. So what are photodiodes, what is their usage and by what parameters are they characterised? Get acquainted with the most important information about products which could be found in our store. We offer various kinds of top quality diodes.

Optoelectronics - Use our products for it

Do you deal with optoelectronics, build devices and circuits that use light properties for various purposes, such as processing and gathering information? Or do you build devices or cameras that emit or sense light? If so, we encourage you to get acquainted with our offer. You will find various kinds of photodiodes which you would be able to use for constructing electronic devices. Our offer consists of THT photodiodes as well as SMD ones.  Thanks to that, depending whether you solder the components yourself, or assemble the PCBs by machines, you will be able to find suitable components in our store.

How a photodiode is built - what does such a component look like?

Photodiodes in their build resemble regular

silicon diodes. They have a flat or convex lens inside which allows it to illuminate one of the circuit's areas. During a regular operation, photodiodes are reverse biased. When it comes to current-voltage characteristics of a photodiode, it is similar to the characteristic of a regular diode. The main difference is the fact that when there is no illumination, a low dark current will be flowing. However after the illumination, an additional  photoelectric current will be present. It is worth mentioning that a photodiode has its own symbol - on every scheme it will be marked by a triangle with a vertical line and two arrows over the triangle. 

Specification and usage of a photodiode

Every component has its own parameters, and photodiodes are no exception here. Among various parameters of components available in our store we could list e.g. photodiode sensitivity, emission spectrum and response time. When it comes to the advantages of photodiodes, high, reaching even hundreds of MHz’s operating frequency and fixed sensitivity to radiation power without a doubt belong to this category. 

Speaking of the usage of photodiodes available in our store, they can be applied in e.g. fast A/C converters, remote control modules, optical switches, and also electronic devices for monitoring electrical and non-electrical measurands. Given that, photodiodes can be used for measuring distances, frequencies, vibration amplitudes and also tension and concentration of solutions.

Photodiode for every need 

In our store you will find a vast variety of various kinds of photodiodes. They will allow you e,g, building optoelectronic devices. Components available in our store can measure infrared elements, vibrations, concentration and many other parameters. Among photodiodes available in our store you will find products from such brands as: OSRAM, Vishay, EVERLIGHT or LUCKY LIGHT. So we are talking about devices from absolute leaders on the market. We make sure that products offered by us have different parameters, just for our customers to find suitable photodiodes for their needs. Those elements may vary in size, temperature range in which they operate, and also wavelength to which they respond. If necessary, we provide advice when it comes to choosing the best photodiode as well as other products.
