Les premierstransistors ont vu le jour en Quelques transistorsanciens au germaniumSi vousvoulez voir d’autres photos de quelques transistors encore plusanciens, allez doncvisiter cettepage. On l’appelle d’ailleurs tout simplement ‘Transistor’. On ne se pose pas trop la question quand onveut utiliser un transistor en commutation lente, par exemple pourpiloter un relais.
Plus letransistor commute vite, et moins on perd de puissance. Commetoujours, tout est relatif.
It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids. A mica insulator electrically isolates the transistor case from the heatsink. It often has a transition frequency of around 3. The frequency at which gain begins to drop off may be much lower, see below. Maximum RatingsThe maximum collector-to-emitter voltage for the 2N, like other transistors, depends on the resistance path the external circuit provides between the 2sc55297 and emitter of the transistor; with ohms a 70 volt breakdown rating, VCER, and the Collector-Emitter Sustaining voltage, VCEO susis given by ON 2s5c297.
Sometimes the VCBO 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. The total power dissipation written PD in most American datasheets, Ptot in European ones 22sc5297 on the heatsink to which the 2N is connected. With an ‘infinite’ heatsink, that is: The device is designed to operate with an efficient heatsink, but care must be taken to mount the device properly, else physical damage or worsened power handling may result, especially with cases or heatsinks that are not perfectly flat.
Other manufacturers around this time also would specify similar values e. RCA by had changed their specification to give 2. Modern 2N datasheets often, but not always, specify fT of 2.
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 phase-shift and open-loop gain even within the audio frequency range.
Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers. History 2N transistors have several applications in power circuits, including inverters and voltage regulators.
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 datasheett.
The team of design, production, and applications engineers received RCA Electronic Dataheet achievement awards in 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.
It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet. Mid sWith changes to semiconductor manufacturing technology, the original process 2ac5297 economically uncompetitive in the mids, and a similar device datashwet created using epitaxial base technology.
Also the higher frequency response has improved performance when used in audio amplifiers. Related devicesVariants with higher voltage ratings e. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N In the sixties and early seventies, Philips produced similar devices encapsulated in TO-3 packages under the reference BDY20 described as being for ‘hifi’ purposes and BDY38 although the BDY38 has lower voltage ratings than the 2N The 2N is a much lower power version of the 2N, rated at 25 W, 55 V 2sc5927 4 A, but became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.
A Tesla KD transistorKD is a higher power equivalent used in Eastern Bloc countries, and is intended for general catasheet applications.

It was produced exclusively by datqsheet Czechoslovakian electronics company Tesla. KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp, 80 volt, watt power transistor. It has a transition frequency of 2. The KD have higher power and higher current than 2N The art of electronics 2nd ed. The robot builder’s bonanza 2nd ed. Graf; William Sheets Build your own low-power transmitters: The 2N, 2N, and 2N devices, for example, which date back to the s but have been improved, are still useful in new designs and are still popular for experimenters.
The current gain, beta, Hfe, is a value you can find in the datasheet for the specific transistor. To calculate for the worst case use the minimum given Hfe value or the correct value for the collector current you need. Vce voltage is the voltage over collector and emitter.
A design guide not included in calculations for now.

Base voltage is the voltage that you use to drive the base of the transistor with. Voltage drop 2s5c297 the Vbe sat value, you will get this from the datasheet looking at the graph for Vbe and Vce sat vs. To insure to turn the transistor fully on, you can double the value for collector current, which will result in a base resistor value half of what this 2sc5279 gives you. The examples are given for the highest collector current and worst case amplification factor, Hfe.
Values for your circuit might vary, be sure to enter values for your own needs. January 27, at I am having trouble finding Vbe sat for a BD in the data-sheet http: I want to drive the transistor using an SG chip and I want to ideally have it passing 2sc527 2 amps for a gate drive transformer.
January 30, at Kind regardsMads Kenneth says: May 21, at Am I doing something wrong? Should I use a 2k instead? Best regardsKenneth Mads Barnkob says: July 20, at July 21, at February 25, at February 26, at April 11, at April 13, at I was wondering if I could use a resistor value lower than datashet I gave double collecter current. I am unsure datasgeet your application, a motor driver will not draw a continues current, but rather 2c5297 with a higher current.
I think you should use the average current, lets say 0. If your logic that switches the base of the transistor can not deliver enough current, a pull-up resistor can be used. Yes you can use other values outside of these ranges, but you risk to be operating in liniar mode if datasheey is too large and thus will slow turn on or if the resistance is too small you will allow more current to be drawn from your driver and it might not be able to do so.

This is were I start building. They suggested I should add transistor TIP32 or something to make it able to use more amperes because now only 0. It is an amateur drawing so be gentle judging it. My first pretty much.
You want the to drive the transistor and the transistor to drive the datasgeet. A base resistor is used to limit the amount of current the have to supply, a that delivers mA is stressed a lot btw.
I would aim for somewhere around a maximum of mA, with a R base resistor and a 10K pull-up you should have 2sc597 sturdy driver for your TIP32C. Kind regardsMads Pete says: April 14, at Your capacitors will be more than happy with datasheey rating. The heavy current only flows from your battery through transistor and into motor. Kind regardsMads aku says: April 19, at Kind regardsMads Constantin Bushofsky says: April 26, at I have a NPN transistor set up with a battery pack at the collector, another battery pack at the base, and an LED at the emitter.
2sc2597 was wondering where I should connect the ground for the battery pack at the datssheet. April 30, at Base current flows from base to emitter in a transitor.
Kind regardsMads Rajesh says: October 9, at Is it really 1 ohm 5 watt as predicted? And is there any other resistor required for collecter also? What about the heat sink?
