Each of the other graph lines are identical between the ‘A’ version and non-A version, so in order to save space the graph showing the other versions of the part are omitted. You mean if I change it to a NPN it will drop only its saturation voltage?

You will not be disappointed with this product, they datazheet very cool and I use them everywhere now. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Jun Sun 26, The typical saturated base voltage of the 2N is shown on a graph at 0.

Google [Bot] and 4 guests. Hope it will perform better than ULN Altogether 64 resisters for 32 columns.

Bluewhiteredor green color Great for shining in from the meter edges from the side or from behind on the base station meters. White Blue red Green. Previous topic Next topic. Originally, it was designed as a “high speed switch”. The graph shown above covers both the 2N and the 2N If you’re covering old transistors, then the dstasheet favorite, for years was the 2N Guideline for ; Derating Electronic Components. They certainly can cover a lot of needs for replacements and projects.

They were quite the marvel in their day.

I paid that princely sum in for the little blue wonder. Orders requiring technical work are shipped in about 3 to 10 days. Heads up- The Price of many China made items went up in price due to tariffs. Transistor Derating Curves Temperature derating is a standard design practice for electrical engineers.

The 2N has a max allowed current of mA and its graph shows a typical saturation voltage loss of 0. Hi I need 4mA of average current. It dtasheet be a mistake to assume that 2N or 2N transistors made today are exactly the same as those made 50 years ago. This is the larger clip in the dual control. Media New media Dataasheet comments Search media. I love these in so dataheet situations. The 2N has a max allowed current of only mA and its typical saturation voltage loss is shown on a graph at 0.

Yes, the PNP emitter-follower has a base-emitter voltage loss and the 74HC adds its output saturation voltage loss. In the heyday of transistor development there were new materials and processes being developed on a seemingly daily basis, to overcome short comings of previous designs, and those new devices deserved their own new shiny type number.

To obtain a higher operational operating temperature apply forced air cooling, the chart covers still air [ Fan Manufacturers ].

S-meter plastic bracket goes around the meter in many, many older radios with S-meters. Datashfet 2N works poorly above 50mA. Suraj Active Member Sep 11, The rest of those characteristics are buried in the 50, or so different transistor types that have been created over the years.

In some circuits these things matter, in others any transistor that meets the minimum spec will work. The 2N 2n294 BC will be a little better.

2N – Retroamplis

Series,andalso datasheet in some others like the Sweet 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. Suraj Active Member Sep 9, I think I could lower down the value of the resistor further!!! But as the OP and others note, there are a number of old types still produced more or less as first introduced, while other classics have succumbed to modern replacements and packaging trends, like replacing the TO Then the base current is only 4.

Up until a few years ago I still had a couple brand new, in the box CKs in my parts inventory, but sadly I’ve lost track of them. Jun Sat 25, Product Description Your Price.

Jun Sun 26, 1: A house number might point to a particular supplier, process, or selection for some particular characteristic–or it may just be a generic part. But it managed to work its way into hobby circles. The line indicating thermal runaway runs out another 10 degrees before dropping, for the ‘A’ version parts, and terminates at degrees centigrade.

TO sounds much better than “Unibloc” – that sounds like a prison section to me. This is the largest clip used for the channel selector knobs. Maybe only the first dozen or so are given on a typical spec sheet.
