New Category – Datasheet Websites

By on October 23, 2009

I have decided to put in a new category in this  blog which is the Datasheet websites. It is important to have such websites in this blog because this would make you to easily locate the components datasheet all under one roof. I will gather all datasheet websites from time to time and if you come across any of these websites please do let me know-thanks! Below is a datasheet website from DATASHEETARCHIVE.COM and in this website if you scroll down on the right you could see a Semiconductor Data Handbook photo. If you click on the data books link below the photo, it will brings you to lots of semiconductor catalogue links.


Another datasheet website is ALLDATASHEET.COM and you may click on the photo to visit the website:

    Hello Jestine, thanks for the site. I found a datasheet on this site just now that I was looking for a long time. It is for a mosfet K3563 and I have now found NTE part 2903 for it. It comes from a TV that is giving me 225V B+ instead of 133V. So when connected it makes a snapping sound. I checked fet as I am not sure what could be causing it.I took out fet to check with analog TY360 Tianyu (9V and two 1.5v batteries). I follow testing procedure according to ebook but I am not sure. When I put finger to drain and gate it moves up a little at 10X. But when I remove probe it goes back down. Do I have to remove my finger before the red probe? Could it be the mosfet?

    Thanks and have a good weekend.

    that what I use all the time to get the data of is very good

    Hi Jorge,

    Certain FET when you place your finger to test it with analog meter, the needle will kick up to the center and then will automatically come down. This is also a good FET characteristic. By the way the increase in B+ voltage could be cause by components in the optoisolator circuit. An open resistor in this circuit can cause the B+ voltage to shoot up very high.

    I use the datasheet archive website. It has been improved recently. There are a few that are good but with only small databases.

    HI Lisa,

    Thanks for the comment. Some database websites exist only to make money from advertisement that's why it don't really have much info in it. I guess at the moment the best is still

    Hi Ronnie,

    Get books on TV repair and make sure you know how to test electronic components.
