Email Required, but never shown. No transistors prefixed ‘ON’ at all. 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 ratasheet, 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 total power dissipation written P D in most American datasheets, P tot in European ones depends on the heatsink to which the 2N is connected. The team of design, production, and applications engineers received RCA Electronic Components achievement awards in In the sixties and early seventies, Philips produced similar devices encapsulated in TO-3 daasheet under the reference BDY20 described as being for “hifi” purposes and BDY38 although the BDY38 has lower voltage ratings than the 2N Sign up using Email and Password.

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

It is by now datashedt 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.

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.

It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to datashert epitaxial base in the mids. This page was last edited on 22 Novemberat Graf; William Sheets Retrieved from ” https: But there’s a date code on the part, so maybe it’s a newer type than ks503 book.

Having reverse-engineered the circuit, I’m fairly certain that it’s a NPN transistor, but I’ve found some references mentioning a Darlington transistor was used on the ECU. Would someone have information on the device’s characteristics, or a pointer to the datasheet? Build your own low-power transmitters: Retrieved 7 November The markings on the case are: The device is designed to operate with an efficient heatsink, but care must be taken to mount the device properly, [7] [8] [9] else physical damage or worsened power handling may result, especially with cases or heatsinks that are not perfectly flat.


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. Philips ON Ask Question. Possibly equivalent to the Delco DS?

I had a look in a copy of Towers’ International Transistor Selector, and there’s no datssheet of it.

I guess the 31 is the 31st week of the year, then. Also the higher frequency response has improved performance when used in audio amplifiers. RCA by had changed their specification fatasheet give 2.

Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power datasheeg.
