865nm IR LED - 3014 SMD LED 0.3W

How do we know a SMD LED IR LED or a through-hole LED is working or not in your cirrcuit? The forward voltage drop of infrared LED is generally 1.3 ~ 2.5v. Because the infrared light emitted by it is invisible to the human eye, the above-mentioned visible LED detection method can only determine whether the forward and reverse electrical characteristics of the basic pn junction are normal, and it cannot be determined whether its light emission is normal.
For this reason, it is best to prepare a photosensitive device (such as 2cr, 2dr silicon photocell) as the receiver. Use a multimeter to measure the change in voltage across the photocell. To determine whether the infrared LED emits infrared light after adding an appropriate forward current. Rarely IR LED include 680nm LED, 720nm LED, 810nm LED, 980nm LED, 1050nm LED, 1300nm LED, 1550nm LED and 870nm LED. These 880nm LED with the shape of 2835 SMD LED are widely used in Medical industry, beauty industry and high and new technology intelligent industry.

The 880nm are invisible IR LED. But in the totally dark night, you can still see the weak red spot in the top of the IR LED.
