Tony Roberts January 6, at This site uses cookies. Note that a reverse biased LED can conduct when light of a suitable wavelength is presented generally centered around the wavelength which that LED emits when normally driven. To drive the LED, it has to be above 1. Not sure if your confusion about which component is which got resolved. It was time to do some tests and measurements. All was fine, until the salesman at the local shop told me:.

Anyway, I purchased them. Probably someone has misplaced them, when restocking. Dimitar Kovachev January 6, at fatasheet Photo diodes have always confused me a bit. When forward-biased, the current through the photo-transistor is proportional to the amount of light. By continuing to use this website, you agree to their use. The LED is blue, the phototransistor is clear. The devices you present here do not appear to have that characteristic. The image sensors pick up IR!

The final datashheet was to take a digital multi-meter DMMset it to current measurement, 20mA range and complete the circuit:. 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: Thanks for writing this up!

How would you go around this issue but with a phototransistor and a photodiode? Mostly harmless… Exploring electronics, programming and photography. Notify me of new comments via email.

Kenneth Olsen January 4, at Under certain conditions, they will conduct electricity. This leads us to our criteria — the current through a forward-biased LED is a constant; the current through fatasheet forward-biased PT varies with light.

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.

Sean Straw July 8, at LEDs and photo-transistors can be wired in a similar way — dataaheet a current-limiting resistor in series. To find out more, including how to control cookies, see here: Leave a Reply Cancel reply Enter your comment here You have 2 LEDs in your picture.

IR LED and a photo-transistor – which is which? So a LED will light and a phototransistor will not. This is a useful way to verify that an IR remote control is in fact transmitting. This can be useful for driving a darlington or as input to an opamp or inamp.

Re-doing the math with these particular values gives the expected current for the LED: Yes it did checked with a camera. When a LED is forward biased, it emits light while the transistor switches and amplifies the colector-emitter current if the base-emitter datazheet is forward biased. It was a photo-transistor. A LED or a phototransistor?! Dimitar Kovachev February 2, at Posted by Dimitar Kovachev. Use your smart phone or camera.
