Key Specifications of 5mm IR LED Datasheet

1. Forward Voltage (Vf): The forward voltage is the voltage required to drive the IR LED. It is an essential parameter to ensure that the LED operates within its specified range. The typical forward voltage for a 5mm IR LED is around 1.2V to 1.5V. 2. Forward Current (If): The forward current is the current that flows through the IR LED when it is forward biased. It is crucial to operate the LED within its recommended current range to prevent overheating and damage. The typical forward current for a 5mm IR LED is around 20mA to 30mA. 3. Maximum Power (Pmax): The maximum power is the maximum power dissipation that the IR LED can handle without causing damage. It is calculated by multiplying the forward voltage and forward current. The typical maximum power for a 5mm IR LED is around 60mW to 90mW. 4. Wavelength: The wavelength of an IR LED determines the color of the emitted light. A 5mm IR LED typically emits light in the near-infrared range, with a wavelength of around 940nm to 950nm. 5. Intensity: The intensity of an IR LED is measured in milliwatts (mW) and indicates the amount of light emitted by the LED. The intensity of a 5mm IR LED can range from 5mW to 30mW, depending on the specific model. 6. Viewing Angle: The viewing angle of an IR LED is the angle within which the emitted light is concentrated. A 5mm IR LED typically has a viewing angle of 20° to 45°.
