About this part
The assembly is what makes this one unusual. The device itself is a small TO-18 style transistor, and it arrived fitted into a metal mounting flange rather than loose. Carriers like that were used where a small can needed to be held to a chassis at a defined position, for thermal contact, for mechanical security under vibration, or simply so a technician could not fit it the wrong way round. The hardware ships exactly as pictured, because separating it would destroy the thing that distinguishes this from any other 2N2280.
Electrically it is modest: about 50 milliamps of collector current, 150 milliwatts, six volts collector to emitter and a transition frequency near 16 MHz. Six volts is the figure to notice. That is a narrow envelope and it will not tolerate being treated as a general purpose device, which is the usual way an old small signal part gets destroyed.
It carries the government stock number 5961-00-734-4623, and historical suppliers of the type include Sprague and Philco Ford. The case reads 2N2280 with 7732 beside it, which on the usual convention points at the thirty second week of 1977. Ordinary scratches, oxidation and storage wear. Untested.
Questions about this part
What is the flange for?
Holding a small can to a chassis at a defined position. Carriers like it were used for thermal contact, for mechanical security under vibration, or so a technician could not fit the device the wrong way round. Which of those applied here is not something the object can tell us.
Can I have it without the hardware?
It ships as pictured. The assembly is what distinguishes this from any other 2N2280, and taking it apart would destroy that for the sake of a part you can buy loose. If you want a bare 2N2280, ask and we will look for one rather than dismantle this.
Six volts seems very low.
It is, and it is the number to design around. This is a small signal switching device with a narrow envelope, not a general purpose transistor, and treating it as one is the usual way an old part like this gets destroyed on the first power up.
What does the NSN buy me?
A direct link to how military and aviation systems order parts. If you are working from a document that lists 5961-00-734-4623 rather than 2N2280, this is that item and you do not have to establish the cross reference yourself.
