Special financing available Select PayPal Credit at checkout to have the option to pay over time. Watch list is full. The 2N remains very popular as a series pass transistor in linear power supplies and is still used in for medium- current and high- power circuits generally, including low frequency power converters although its use in audio power amplifiers and DC-to-AC inverters is now less common and its use in higher frequency switch-mode applications never was very practical.


The KD have higher power and higher current than 2N This item will be shipped through the Global Shipping Program and includes international tracking. The 2N is a much lower power version of the 2N, rated at 25 W55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.

The historically-significant 2N was designed by Herb Meisel’s engineering group with RCA; it was the first multi-amp silicon power transistor to sell for less than one dollar, and became an industry workhorse standard.


New and original ic electronic component transistor 2N3955

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.

Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers. The 2N, 2N, and sppec devices, for example, which date back to 2j3955 s but have been improved, are still useful in new designs and are still popular for experimenters.
