It would be very helpful if you would describe the package, application, and provide a photo. I don't think you're reading the part number or manufacturer correctly. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Basic information:
What is it? What is it from? What does it do? What does it look like? Example: The ON datasheet number for a 2N3772 NPN power transistor is: MJ15022. Their part number is: MJ15024G. Peter Wieck Melrose Park, PA |

It's on a dashboard PCB from a Lincon Navigator, it seems to be a one of a identical pair of switchers driving a transformer primary. Here's an identical one to mine: http://www.tehnari.ru/f39/t256954/ Thanks. |

CQ may indicate an automotive grade. RL |

Here's an identical one to mine: http://www.tehnari.ru/f39/t256954/ Well, that certainly is a readable ON Semi part number. That package is a TO-220: https://www.onsemi.com/pub/Collateral/221A-09.PDF with a "style 1" pinout where the silk screened ECB suggest a bipolar power transistor. The problem is that searching the ON Semi web pile yields a clock generator and a tiny SOT-23 MOSFET, neither of which is available in a TO-220 style case. There is such a thing as a 2N5105, but it's an ancient low power JFET in a small TO-72 can. Dead end, I guess. Back in the stone age, I would have taken the possibly matching device, put it on a transistor curve tracer, and tried to deduce the device characteristics. There daze, there are so many different transistors, that such an exercise would probably be futile. I suggest you try to find a repair shop that refurbishes automotive electronics. https://www.google.com/search?q=lincoln+navigator+refurbished+dashboard+m odules or buy something from your neighborhood chop shop (used auto parts dealer). -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I've been down that road myself before I asked here. I de-soldered the transistor that appeared undamaged to see if it would help me guess at a replacement and the device turned out to be an np diode - the base emmiter junction is no longer with us. Thanks for your efforts. |

I've hit a blank everywhere else, so a suck-it-and-see lucky guess substitution attempt is my next move. I've got some TIP31Bs - I'll let you know if your guess wins ;-) Cheers. |
