AdjusterJan 15, AdjusterJan 12, I believe it is the pin that juts out a little bit, which should be the base pin I have marked my guess in the photo attached. Let us trash the safety issues as of phototransisyor. My first guess would be that the base could be left open, but depending on the application it may be better to connect a resistor from the base to the emitter. Jan 13, 6.
Using a L14F1 IR phototransistor in a switch
This was exactly why I asked a circuit diagram. Jan 12, 2. Lastly, I don’t allow my lack of skils to come in between me making my circuit. Jan 12, 4. AdjusterJan 13, Join L14g1 Forums Today!

If not, I don’t mind, a little bit of trial-and error can be done. I would guess that by 3-pin you mean a device which has the base connection brought to an outside pin, since LIF41 is a photo-darlington which has the input base brought out? I believe soldering shouldn’t be much of a safety concern as I have used them before and have gone for a robotics phototransishor wherein we had to solder the parts provided onto the provided PCBs in a way, they didn’t explain how they work, but just doing the soldering.
This would help against leakage effects and improve turn-off speed, at the expense of lowered sensitivity. By the way, could you tell why the resistor is used in the circuit? Log in or Sign up. Like the earlier one I posted, why couldn’t I just leave one pin left out hanging? Everyone who loves science is here! As a final help, in the picture of the phototransistor product I have attached, please look at it and phototrajsistor it to me if you can identify the base pin.
And never mind the time, my parents decided to buy the phototransistor later.
Jan 15, In another posting I also sent you phototransistof link to a data sheet for the L14F1. Hello univeruser Since you have said that you don’t want to make any more sensitive arrangements, here is a simple diagram adapted from what you originally uploaded, showing the photodarlington transistor driving a LED – in this phototrqnsistor, the ohm resistor is needed. I just suggested a remote control car with it, but I could rather make a simple wireless circuit switching a bulb off and on.
Using a L14F1 IR phototransistor in a switch. Last edited by a moderator: Secondly, I don’t want to make more sensitive arrangements, for Phototrnsistor can easily afford to point 1l4f1 laser pointer on the phototransistor, even if impractical.
No, create an account now. My father told the transistor may fry up at excess voltage, but is it right? Could you please post a diagram and fuller details of your application? You will see that the transistor base lead is not connected, as was suggested in one of my earlier posts. Yes, my password is: The friendliest, high quality science and math community on the planet!

I suggest that you look at that because amongst other things it will show you how to connect the device up correctly. Phototrransistor 13, 9.
Jan 14, But then, which one? Your name or email address: Jan 13, 8. Jan 12, 1. Do you already have an account?
So again, I hope the diagram will be posted without further questioning.
