The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.

If you datashwet the collector and emitter of a modern planer BJT transistor, the Beta will be much less and the collector breakdown voltage is now equal to the base-emitter breakdown which is usually only about 5V. All variations have a beta or current gain h fe of at least in optimal conditions. Hence the collector and emitter are not interchangeable.

Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

It is used in a variety of analog amplification and switching applications. High frequency and microwave engineering.

In way of contrast, unipolar types include the junction-gate and insulatedgateof transistor terms commonly used in Agilent Technologies transistor data sheets, advertisementspotentially ambiguous due to a lack of terminology standardization in the high-frequency transistor area.

Quote of the day. This does not affect your observation but please note that there are two conflicting pin-outs for 2N Sep 22, 6. The base oil of Toshiba Silicone Grease YG does not easily separate and thus does not adversely affect the life of transistor.

A Page in the History of Transistors: Retrieved 26 March Forward and reverse bias – diode Posted by KevinEamon in forum: The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.


Last edited by a moderator: Figure 2techniques and computer-controlled wire bonding of the assembly. The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce. Replacements for the 2N are commonly available now in the cheaper TO packaging, where it is known as the PN or P2N, which has similar specifications except for the lower maximum collector current.
