Please contact authorized Vishay personnel to obtain written terms and conditions regarding products designed for such applications. Please note that some Vishay documentation may still make reference. For definitions of compliance.
The relevant curves from the datasheet specified with a known reflectance are below: Email Required, but never shown. What is a CNY70 sensor?
CNY70 product information
The CNY70 is a reflective sensor that includes an infrared. I couldn’t find anything about the ON state resistance of the datasyeet, which could make things much easier for me. For most practical purposes this device is not going to do a good job of driving an LED directly. I couldn’t find anything about the ON state resistance of the transistor, which espall 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.
It’s more like a current source until Vce drops to below a volt or so.

Email Required, but never shown. Today with your help, I learned that there are photoresistors around and work quite different than bipolar transistors: The relevant curves from the datasheet specified with a known reflectance are below:.
Reflective Optical Sensor with Transistor Output. That means that a typical unit will pass about 1mA datazheet the transistor. Please provide a schematic for this purpose Link to datasheet: I know this because I have used them occasionally since long long long ago and they do work.
