The main problem is that I don’t understand much from the CNY70’s datasheet. I couldn’t find anything about the ON state resistance of the transistor, which could make things much easier for me. Could you please explain what calculations should I do, or which figures should I check in the data sheet in order to calculate the X resistance value for safe operation.

The transistor does not behave like a resistor. It’s more like a current source until Vce drops to below a volt or so.

Problem in CNY70 sensor – Electrical Engineering Stack Exchange

The relevant curves from the datasheet specified with a known reflectance are below:. That means that a typical unit will pass about 1mA through the transistor. The transistor will bottom out at mV or so.

If your application does not have the 0. This indicates how much current the transistor should pass, for a given LED current. In the “Basic Characteristics” table, the first line indicates that the typical transistor current is 1 mA with an LED current of 20 mA, when viewing a white card.

Please keep in mind that, I’m quite a newbie in electronics Thank you. Xcodo 4 SoajanII 12 1 6.

The relevant curves from the datasheet specified with a known reflectance are below: Spehro Pefhany k 4 Did you use Fig. There is only a typical 1mA a minimum 0. I would guess that most units are between 0. Accidentaly removed my question: You shouldn’t think of “on state resistance” of a bipolar transistor.

Wish I could have enough reputation to upvote.

Today with your help, I learned that there are photoresistors around and work quite different than bipolar transistors: Sign up or log in Sign up using Google. Sign up using Facebook.
