Definition and Characteristics of 5mm IR LED Voltage

The 5mm IR LED voltage refers to the forward voltage required to make a 5mm infrared light-emitting diode (LED) operate at its rated current. Typically, the forward voltage of a 5mm IR LED ranges from 1.2V to 1.8V, depending on the specific model and manufacturer. The forward voltage is an essential parameter because it determines the amount of power required to drive the LED and the efficiency of the circuit. The 5mm IR LED has several characteristics that make it widely used in various applications. Firstly, it is compact in size, measuring only 5mm in diameter. This compact size allows it to be easily integrated into various devices, such as remote controls, cameras, and sensors. Secondly, the 5mm IR LED emits infrared light with a wavelength of approximately 940nm, which is invisible to the human eye. This makes it suitable for applications where invisible light is required, such as night vision devices. Lastly, the 5mm IR LED has a long lifespan, typically ranging from 20,000 to 50,000 hours, which ensures its durability and reliability in long-term use.
