The datasheet contains vital information such as the LED's forward voltage, forward current, light output, and wavelength, among other parameters.

Key Parameters of 5mm IR LED Datasheet

1. Forward Voltage (Vf): The forward voltage is the voltage required to drive the IR LED at its maximum forward current. This parameter is crucial for determining the appropriate power supply and circuit design. The typical Vf for a 5mm IR LED ranges from 1.2V to 1.5V, depending on the specific model and manufacturer. 2. Forward Current (If): The forward current is the maximum current that can be safely passed through the IR LED without causing damage. It is essential to operate the LED within its recommended current range to ensure optimal performance and longevity. The typical If for a 5mm IR LED is between 20mA and 100mA. 3. Light Output (Luminous Intensity): The light output is a measure of the intensity of the infrared light emitted by the LED. It is usually expressed in milliwatts (mW) or milliwatts per steradian (mW/sr). The light output of a 5mm IR LED can range from 5mW to 100mW, depending on the model and manufacturer. 4. Wavelength: The wavelength is the color of the light emitted by the IR LED. 5mm IR LEDs are typically available in three primary wavelengths: 940nm, 870nm, and 780nm. The choice of wavelength depends on the specific application and the required detection range. 5. Viewing Angle: The viewing angle is the angle within which the IR LED emits light with a certain intensity. It is usually measured in degrees and can range from 20° to 120°. A narrower viewing angle results in a more focused beam, while a wider angle provides a broader illumination area. 6. Thermal Resistance: The thermal resistance is a measure of how well the IR LED dissipates heat. It is typically expressed in degrees Celsius per watt (°C/W). A lower thermal resistance indicates better heat dissipation and higher reliability. 7. Operating Temperature Range: The operating temperature range is the range of temperatures within which the IR LED can function without damage. It is essential to ensure that the LED operates within this range to maintain its performance and longevity.
