I’ve never really understood why there needs to be 50, different transistor types or whatever the number isbut it’s nice to see a few types stand the test of time. It would be a mistake to assume that 2N or 2N transistors made today are exactly the same as those made 50 years ago. For me its base current will be Its max base-emitter voltage is 2. The 2N is obsolete and is in an old metal case. I remember when 2N, 5 germanium were popular.

2N2904 Datasheet

Again, how much will be its maximum current? I paid that princely sum in for the little blue wonder. West-Cap polyethylene capacitors 0. Orders requiring technical work are shipped in about 3 to 10 days.

To completely characterize a bipolar junction transistor you need more than 40 parameters. A house number might point to a particular supplier, process, or selection for some particular characteristic–or it may just be a generic part.

Thread starter Suraj Start date Aug 16, The 2N has a max allowed current of only mA and its typical saturation voltage loss is shown on a graph at 0. Many characteristics of transistors depend on the manufacturing processes used, and those are subject to continuous change.

Also great for RobynComstat and many other tube radios. The datasheet of the 2N NPN transistor shows a max allowed current of mA and poor performance above about 50mA.

Replacement Transformer Started by ncag Today at 7: Jun Sun 26, 2: Jun Sat 25, Click here to register datzsheet. A 2N works poorly above 50mA. The graph only applies to a TO metal package, but a 2N is also available in a plastic TO package.

Jun Sun 26, This is the largest clip used for the channel selector knobs. Product Description Your Price. Here how I did. Here’s part of an older datasheet: Pretty nifty that they are still being made and designed into new products. Yes, the PNP emitter-follower has a base-emitter voltage loss and the 74HC adds its output saturation voltage loss.

Users browsing this forum: Bluewhiteredor green color Great for shining in from the meter edges from the side or from behind on the base station meters. Previous topic Next topic. Jun Sun 26, datasgeet I use 2N and 2N all the time. Suraj Active Member Sep 9, You mean if I change it to a NPN it will drop only its saturation voltage?

Datasheets, Manuals or Parts. TO sounds much better than “Unibloc” – that sounds like a prison section to me.
