BPV11 Phototransistor pinouts and sample circuit

Former Member

I am using a BPV11 photo-transistor to sense ambient light.

 

I cannot find a data sheet with pinouts or a sample circuit. I have used other photo diodes and LDRs before.

 

Thanks,

    Page 4 has the pinout:

    Thanks Joern (Joerg).

     

    I have had a good session with the wash cloth getting rid of that egg on my face:-).

     

    The data sheet was the first place I went (I am good at reading the manual) and I read through it many times. I even got on the web and found many copies of the same Vishay data sheet scanning it each time but probably with less attention to what I was looking for. I was just getting frustrated seeing only the one data sheet and still I could not find the pinouts.

     

    When I saw the reference to "page 4" I figured, maybe, I missed it after all.

     

    And there it was. Plain as day.

     

    I can only say in my defense that I "assumed" it would be on the first page (with the photo) or maybe second page. After that I almost certainly rushed through the "technical stuff" of graphs and specs and my brain didn't find what it "knew" wasn't there:-(.

     

    Thanks again for taking the time to help out an old (73) techo still very active with microprocessor (PIC) projects.

     

    And, I had also assumed (incorrectly) that the middle pin would be the base pin as it is mostly not provided with photo transistors. When I plodded along trying each combination of two pins until I got a light response I found the correct pinouts and successfully incorporated the BPV11 into my project.

     

    A very grateful,

    And apologies to the CadSoft Eagle folks for posting this question in the wrong place.

     

    I am a long time Element14 customer but using the forum for the first time.
