Modern 2N datasheets often, but not always, specify f T of 2. See other items More This is a private listing and your identity will not be disclosed to anyone except the 2m3955.

Transit times may vary, particularly during the holiday season.

Sometimes the V CBO breakdown voltage the maximum voltage between collector and base, with the emitter open, an unrealistic arrangement in practical circuits is given as the only voltage rating, which can cause confusion. From Wikipedia, the free encyclopedia. Add to watch list Remove from watch 23n955.

Nevertheless, a 2N and many other power transistors originating from this era cannot be assumed to have great high-frequency performance and there can be degradation of s;ec and open-loop gain even within the audio frequency range.

Subject to credit approval. It is by now unlikely to actually obtain a genuine 2N transistor when using popular sales platforms such as Amazon or Ebay; classic electronics distributors are mostly still able to properly source them.

Although the original 2N went into decline relative to epitaxial-base transistors because of high manufacturing costs, the epitaxial-base version continued to be used in both linear amplifiers and switching supplies.

Orders processed within hours of payment verification. RCA by had changed their specification to give 2. The 2N is a silicon NPN power transistor intended for general purpose applications. The 2N is a much lower power version of the 2N, rated specc 25 W55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.

It often has a transition frequency of around 3. The maximum collector-to-emitter voltage for the 2N, like other transistors, depends on the resistance path the external circuit provides between the base and emitter of the transistor; with ohms a 70 volt breakdown rating, V CERand the Collector-Emitter Sustaining voltage, V CEO susis given by ON Semiconductor.
