Introduction to 5mm IR LED Datasheet

A 5mm IR LED datasheet is a technical document that outlines the characteristics, specifications, and performance of a 5mm infrared light-emitting diode. It serves as a reference for engineers and designers to understand the capabilities and limitations of these devices. The datasheet typically includes information such as the forward voltage, forward current, peak wavelength, radiant intensity, and viewing angle of the IR LED.

Understanding the Specifications

To make the most out of the 5mm IR LED datasheet, it is crucial to understand the key specifications mentioned in the document. Here are some of the important parameters:

1. Forward Voltage (Vf): This is the voltage required to drive the IR LED and make it emit light. The forward voltage of a 5mm IR LED is usually around 1.2 to 1.4 volts.

2. Forward Current (If): The forward current is the current required to operate the IR LED. It is typically specified in milliamperes (mA). For a 5mm IR LED, the forward current is usually between 20mA and 30mA.

3. Peak Wavelength (λp): This parameter indicates the color of the emitted light. For 5mm IR LEDs, the peak wavelength is usually around 940nm, which is in the near-infrared region of the electromagnetic spectrum.

4. Radiant Intensity (Ie): Radiant intensity refers to the total amount of light emitted by the IR LED. It is measured in milliwatts (mW) and is an important parameter for determining the efficiency of the LED.

5. Viewing Angle: The viewing angle is the angle within which the IR LED emits light. It is an essential parameter for determining the coverage area of the light. For 5mm IR LEDs, the viewing angle is typically around 30° to 45°.
