I'm trying to identify a transistor marked F585 ...

[kooth]

Hello all,

This is my first post here! This is a great site: a wealth of knowledge!

I have several old transistors that are marked in the following manner:

F585
-33
831 (or possibly 837)​

I am able to test it with my multimeter and I know that it's an NPN with an hFE around 76, but that's about all I'm able to ascertain. Does anyone have any idea of where I can find more information about these little guys? I'd love to find a datasheet of course, but any information will be welcome!

Thanks so much in advance,

Keith E. Cooper

Is this the part that you are talking about? BF5885

Hey, thanks Dragon Tamer! I should have stated that what I'm looking for is in a TO-92 package. But Philips may be the answer! I've had these little guys for at least 30 years -- probably closer to 40 years.

I really appreciate your effort in trying to help!

I have attached (hopefully) a couple of images.

Sincerely,
Kooth
