    Bridge rectifier identification part number KPB305G

    Hi all, a newby question about a bridge rectifier I'm trying to identify.

    I'm in the midst of reparing a battery charger in work which went pop, The bridge rectifier has shorted and took out a couple of other components. The rectifier in question has a part number KPB305G, and it looks like it's obsolete. Does any one know what I could replace it with?

      KBP bridge rectifiers are 3A and I find not so popular outside of Asia.
      The "305" is 3A and oddball numbering for a 600V part, other manufacturers use "306". You can use a higher voltage part like KBP306, 308, 310 etc. much easier to find.

      The fuse should have protected it, and there may be an overload or short on the primary like a blown mosfet.

        Thank you, I have a look for one of those.

        The fuse and mosfet were blown, also a exploded resistor which were replaced. But I still had a short, which I traced to the rectifier.

          Smd code to part number
          by esinior
          Hi i have a smd part with probably mark "QO 11" or "Q0(zero) 11" on it, and its package is SOT89, i doubt its KTB1260 PNP transistor, but in measuring with diode mode of multimeter it shows number 1.4 between emitter and collector pins and its not open circuit, and .59 from collector to base and .8 from emitter to base , and these numbers doesn't match a pnp transistor, i couldn't find any part number and datasheet for it, does anybody have information for that part number?
          I've attached pics of this part
          Thanks...

          Panasonic part number in service manuals
          by Yanleb
          In the Panasonic service manuals, both in the board schematics and in the part listing, the part numbers that are given are Panasonic part numbers instead of the actual part numbers.

          This is especially annoying for small SMD components like diodes and transistors when you only have 1-3 digits printed on the component body.

          For an example, look at the attached PDF.

          Do you have a way to cross reference the Panasonic part number with the actual part number?

          Thanks....

          KingWin ABT-650MM 650 Watt ATX PSU [PCB: SW8835REV:A]
          by momaka
          For today's thread, I have a KingWin ABT-650MM ATX PSU. Official web page with the PSU specs is still up and can be found here:
          http://www.rmac.kingwin.com/products.../abt_650MM.asp

          I just can't help it when I see a broken / for parts PSU on eBay that's listed for cheap and looks at least somewhat interesting. Well, OK, I won't lie – on the outside, this PSU looks anything but interesting. It's a plain gray box with colorful “spaghetti cables”.




          What mostly drew me into buying it is its 2x PCI-E power connectors...

          Acer nitro 5 AN517-54-71TL Gh53g-LA-L191P Part identification
          by Viktor Árvai
          Hi !
          I would need some help in part identification , on a GH53G-LA-L191P motherboard , i have downloaded a boardview file from here for LA-L191P there are some difference but essentialy its the same on this file it shows prm6 i would like to know the value of that resistor i think.
          Thank you !...

          Fujitsu Q556, What capacitor for bridge rectifier?
          by mpn78
          Hello

          My Fujitsu Esprimo Q556 motherboards blew up. At least fuse, bridge rectifier and capacitor got damaged. I have changed fuse and bridge rectifier (DF1508S), but I don't know what capacitor it is (picture). I know that capacitors size is 47nF, but I don't know other specs for it. Can you help me to choose right capacitor for my motherboard?
          There is 240V AC on input side of bridge rectifier and 340V DC as output on capasitors side.

          Thanks....
