    Good OEM 2N3771 transistors

    Brand new, prime ST Microelectronics parts. Used these to replace shorted parts in a 40A power supply. They worked perfectly.

  • Most critical review

    2N3771's I received failed immediately.

    The 2N3771 parts I received when place in a power supply all failed immediately. Further investigation, pulling the top of the TO-3 Case, reveled a small chip with tiny lead wires. I measured the diameter of the about wirebonds to be 0.006". These lead wires will fuse at ~4A which is totally unsuitable for a 30A part. The silicon chip area was about 2mm x 2mm compared to a chip area of about 6.5mm x 6.5mm on the original 30 year old 2N3771 parts I was trying to replace. Using NTE 2N3771's fixed my power supply - so problem was NOT my power supply.

  • seem to be good

    I have tested the hfe of these and they test good. I will eventually use them to repair a couple of power supplies (pass transistors)- these have good reviews from other users.

  • Good quality transistors

    This appears to be a very good 2N3771 transistor compared to some of the other ones out there. Great for use in power supply that used them originally.

  • They work

    They work for what I needed. Used them to repair my 12v 20A radio power supply. Cost a lot less than a new power supply. Johnnie
