So a funny thing happened to me at the 'flea at MIT' , i came home with something i cant identify. - ok probably not that big a surprise. but how could i pass up a bag of transistor looking devices thrown into a deal. these are marked 8470-1GE (or maybe its 'ige' or LGE) - see pics the transistor tester definitely isn't identifying these right, - hfe of 13k? its doubtful these are BJT transistors. i literally have a bag of 1000's of these, maybe even 10,000 hard to judge. it be nice to identify them, otherwise there just gonna be trash. so far my internet searches have come up empty. maybe its some company specific part number. anyone have any ideas. |

Can they be darlington transistors? Open one up and see how it look on the inside. Also, assume this tester is correct, and use one as a transistor in a circuit, and see what happens. And I bet they are worthless, regardless of what they are. They may contain some precious metals, so they may be worth something as scrap. |

hmm, didn't think of them being Darlington's yea not like trying to make money off them, heck id be happy if there useful, id hand them out like candy lol. |
| innkeeper:
the insides as best i could get |

My guess: old germanium transistor manfactured by General Electric I wouldn't trust the tester here. You may want to check them using the "conventional" method (diode tester from multimeter), see what the real Vbe is. |
