What is IR photodiode?
An IR sensor is basically a device consisting of a pair of an IR LED and a photodiode, collectively referred to as photocouplers or optocouplers. The IR LED emits IR…

This area cover defination of photodiode, working principle of photodiode and some basic question on photodiode works in circuit.
An IR sensor is basically a device consisting of a pair of an IR LED and a photodiode, collectively referred to as photocouplers or optocouplers. The IR LED emits IR…
An avalanche diode is a special type of semiconductor device designed to operate in the reverse breakdown mode. Avalanche diodes are used as over pressure valves (a type of valve…
Photodiode is A photodiode is a semiconductor device that converts light into electrical current. The current is generated when photons are absorbed in the photodiode. Photodiodes can contain optical filters…
A solar cell also converts light energy into electrical energy. It’s basically a large-area photodiode. Main difference between solar cell and photodiode: Solar cells are more concerned with the amount…
Photodiodes more effectively convert incident light into electrical current in the off-state than in the off-state, as the width of the stopband increases as you increase the blocking voltage –…
The photodiode is widely use in day to day life means in consumer electronics and in industry. Application of photodiodes. The photodiode is used in an optical communication system. The…
In most circuits, you can replace a standard silicon photodiode with an LED. Pay attention to the polarity. Also keep in mind that the LED is not as sensitive as…
LEDs can also be used as photodiodes because they can emit and sense light from their junction. All PN junctions are photosensitive and can be used in a photoconductive, undistorted…
A photodiode may be used to detect optical signals as we observe the change in current with change in light intensity when a reverse bias voltage is applied. Under a reverse…
One of the major differences between the photodiode and the phototransistor is that the photodiode uses a PN junction diode that converts the light energy into electrical current while the…
