It was a photo-transistor.
The devices you present here do not appear to have that characteristic. To find out more, including how to control cookies, see here: Mostly harmless… Exploring electronics, programming and photography.
Low voltage. Mostly harmless…
Yes it did checked with a camera. Under certain conditions, they will conduct electricity. Thanks for writing this up! It was time to do some tests and measurements.
Photo diodes have always confused me a bit. This can be useful for driving a darlington or as input to an opamp or inamp.

Skip to navigation Skip to main content Skip to primary sidebar Skip to secondary sidebar Skip to footer Low voltage. IR LED and a photo-transistor – which is which? Tony Roberts Dataaheet 6, at When forward-biased, the current through the photo-transistor is proportional to the amount of light. Probably someone has misplaced them, when restocking.
So a LED will light and a phototransistor will not. Anyway, I purchased them.

Petes March 2, at The image sensors pick up IR! A LED or a phototransistor?! Note that a reverse biased LED can dagasheet when light of a suitable wavelength is presented generally centered around the wavelength which that LED emits when normally driven.
Sean Straw July 8, at Email required Address never made public. Re-doing the math with these particular values gives the expected current for the LED: Posted by Dimitar Kovachev. You are commenting using your Facebook account.

Sean Straw May 12, at 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.
When a LED datqsheet forward biased, it emits light while the transistor switches and amplifies the colector-emitter current if the base-emitter junction is forward biased. Use your smart phone or camera.
