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.

Not sure if your confusion about which component is which got resolved. By continuing to use this website, you agree to their use.

Sean Straw July 8, at The image sensors pick up IR! Skip to navigation Skip to main content Skip to primary sidebar Skip to secondary sidebar Skip to footer Low voltage.

Sean Straw May 12, at It was a photo-transistor. Petes March 2, at 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. A LED or a phototransistor?!

LEDs and photo-transistors can be wired in a similar way — using a current-limiting resistor in series. Both pt and led as with photodiodes are composed of pn junctions and should datashret light up when forward biased to greater than their turn-on voltage. The devices you present here do not appear to have that characteristic. You have 2 LEDs in your picture.

Under certain conditions, they will conduct electricity.

Tony Roberts January 6, at Dimitar Kovachev February 2, at 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. Re-doing the math with these particular values gives the expected current for the LED: Leave a Reply Cancel reply Enter your comment here You are commenting using your WordPress.

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: This can be useful for driving a darlington or as input to an opamp or inamp.
