Not sure if your confusion about which component is which got resolved. Re-doing the math with these particular values gives the expected current for the LED: This site uses cookies. Both pt and led as with photodiodes are composed of pn junctions and should theoretically light up when forward biased to greater than their turn-on voltage.

To drive the LED, it has to datawheet above 1. The image sensors pick up IR! When a LED is forward biased, it emits light while the transistor switches and amplifies the colector-emitter current if the base-emitter junction is forward biased.


Posted by Dimitar Kovachev. The LED is blue, the phototransistor is clear. When forward-biased, the current through the photo-transistor is proportional to the amount of light. Sean Straw July 8, at Photo diodes have always confused me a bit. This leads us to our criteria — the current through a forward-biased LED is a constant; the current through a forward-biased PT varies with light.

The devices you present here do not appear to have that characteristic. To find out more, including how to datasheeet cookies, see here: Thanks for writing this up!

IR LED and a photo-transistor – which is which? Kenneth Olsen January 4, at Under certain conditions, they will conduct electricity.

dxtasheet Chanced upon this post, and while the proper testing of the components to electrically differentiate the two is useful knowledge, but thought it worth mentioning: You are commenting using your Facebook account.
