The datasheet typically includes information such as the forward voltage, forward current, radiant intensity, viewing angle, and thermal resistance, among others.

Key Features of 5mm IR LED Datasheet

1. Forward Voltage and Forward Current: The forward voltage is the voltage required to turn on the IR LED, while the forward current is the current that flows through the LED when it is turned on. These two parameters are critical for determining the power supply requirements and the operating conditions of the IR LED. 2. Radiant Intensity: The radiant intensity refers to the amount of light emitted by the IR LED in a specific direction. It is typically measured in milliwatts (mW) and is an essential parameter for evaluating the IR LED's ability to illuminate a target. 3. Viewing Angle: The viewing angle is the angle within which the IR LED emits light with a certain intensity. It is an important factor to consider when designing systems that require specific light distribution patterns. 4. Thermal Resistance: The thermal resistance indicates the ability of the IR LED to dissipate heat. A lower thermal resistance means better heat dissipation, which is crucial for ensuring the longevity and reliability of the device. 5. Emitting Wavelength: The emitting wavelength is the color of the light emitted by the IR LED. Common wavelengths for 5mm IR LEDs range from 780nm to 940nm, with 830nm and 940nm being the most popular. 6. Package Type: The package type refers to the physical form of the IR LED, such as TO-5, TO-18, or SMD. Each package type has its own advantages and disadvantages, which should be considered when selecting the appropriate IR LED for a specific application.
