Am I missing something here? This is true of almost all modern transistors a few are made more symmetrical. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: What do you think? The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

Use dmy dates from July Commons category link is on Datqsheet. The 2N exhibits its dztasheet gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce. If it is to replace a shorted transistor, we will never know if both are the same ebc configuration between your new 2N and the old 2N TL — Programmable Reference Voltage.

Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors.

The exact specifications depend on the manufacturer, case type, and variation. No other pin will show that. It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped.

The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor. This transistor will make it forward biased and thus closes the connection between collector and emitter.

All variations have a beta or current gain h fe of at least in optimal conditions. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. In actual circuit modifications might be required. Try not to touch the transistor while testing it because temperature will change the voltage readings. Spehro Pefhany k 4 The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor.

This page was last edited on 25 Octoberat The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. 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.

Wikimedia Commons has media related to 2N Note that the motor here draws about mA from the 12V power source, since the 2N has collector current rating upto mA this circuit is possible had it been a BC the transistor should have been burnt.

The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. I am trying to figure out what is going on here. I have datazheet simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. I have used a base voltage of 5V and a value of 1K as current limiting resistor.
