L14F1 PHOTOTRANSISTOR PDF

L14G2/G3 is an NPN phototransistor. It acts as a photodetector in the sense that it can convert the incident light into electric response. They are commonly used. L14G2 is an NPN photo-transistor. It acts as a photo-detector in the sense that it can convert the incident light into electric response. They are commonly used as . Buy L14F1 with extended same day shipping times.

Using a L14F1 IR phototransistor in a switch

Could you please post a diagram and fuller details of your application? My first guess would be that the base could be left open, but depending on the application it may be better phottoransistor connect a resistor from the base to the emitter. As a final help, in the picture of the phototransistor product I have attached, please look at it and re-post it to me if you can identify the base pin.

Jan 12, 5. I just suggested a remote control car with it, but I could rather make a simple wireless circuit switching a bulb off and on. AdjusterJan 15, Everyone who loves science is here!

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? Lastly, I don’t allow my lack of skils to come in between me making my circuit. Do you already have an account? But then, which one? You will see that the transistor base lead is not connected, as was suggested in one of my earlier phototeansistor.

Like the earlier one I posted, why couldn’t I just leave one pin left out hanging? Secondly, I don’t want to make more sensitive arrangements, for I can easily afford to point the laser pointer on the phototransistor, even if impractical.

Let us trash the safety phototransistr as of now. Jan 12, 4. So again, I hope the diagram will be posted without further questioning. Jan 14, Using a L14F1 IR phototransistor in a switch. In another posting I also sent you a link to a data sheet for the L14F1.

I believe soldering shouldn’t be much of a safety concern as I have used them before and have gone for a robotics class wherein we had to solder the parts provided onto the provided PCBs in a way, phototgansistor didn’t explain how they work, but just doing the soldering. My father told the transistor may fry up at excess voltage, but is it right?

Your name or email address: And never mind the time, my parents decided to buy the phototransistor later. No, create an account now. 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. This would help against leakage effects and improve turn-off speed, at the expense of lowered sensitivity. L14r1 Physics Forums Today! Jan 13, 7. Jan 13, 8. Jan 12, 2.

L14F1 Phototransistor

This was exactly why I asked a circuit diagram. AdjusterJan 13, By the way, could you tell why the resistor is used in the circuit? Jan 12, 3. I suggest that you look at that because amongst other things it will show you how to connect the device up correctly.

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 case, the ohm resistor is needed.
