Help with part identification?

OEM = 2N6055

OEM = 2N6056

You'd have better luck refering to the mfr of the device they are/were used in. Motorola, TRW, NEC and others produced house-coded devices for many industrial mfrs of medium and low power medium wave, VHF and UHF transmitters. Cable companies, mobile, cellular repeater, etc.

Just the application may be enough to tell you basic info, like operating voltage and typical frequency range. The package shape is another clue.

~ 46110 was an Acrian 28V hermetic microwave device with 8-32 stud and

5.7mm x 26.5mm crossed-lead foil structure. Possibly an original device that the house number developed from? (also made close electrical variants 46112, 45113 etc.

~ 1854 sounds more like a linear hybrid amp module (many pins straddling a heatsink bar interface).

Like you, I'm just guessing.

FYI, obscure part numbers can sometimes be crossreferenced here:

1854-0774 = 2N6056

4-611 isn't an HP house code.

1854-0611 = 2N6055

Some HP parts have an abbreviated part number printed on the case, but the parts list contains the full number.

What's that saying? "It's better to be lucky that good..."

Thanks again.

Thanks for the link - I'll bookmark it.

No problem. I hope you get it working.

BTW, if you run across any HP semiconductors that are not listed on that web page, please let me know so that I can update it. A 400 DPI B&W 2 color scan of the parts list is preferred so I can use scan to text conversion, but anything is useful. I would like to add the model numbers that oddballs were used in.

After you pointed me in the right direction, I discovered this:

See pages 3 through 13. Would this be useful? (There might be other useful stuff on the hparchive.com site. It's basically a hobbist / collector site, with no affiliation with HP or the Agilent spin-off.)

Some time ago, a group of us at aus.electronics scanned and OCRed a HP document. This is the result:

Be aware that it may contain OCR errors, eg an I (eye) mistaken for a

1 (one), or an O (oh) for a 0 (zero), etc.
