Talk:NPN

I'm not sure how appropriate it was for me to add the mnemonic but I thought it might add to understanding and identifying a NPN BJT. Feel free to edit or suggest changes. B.K. 03:23, 18 March 2006 (UTC)[reply]

This article is factually inaccurate:

1. NPN is not an abbreviation for "positive-neutral-positive"

2. The letters NPN refer to the majority charge carriers inside the different regions of the transistor, not the materials used to make it

3. Most BJTs used may be NPN, but this statement does not hold true for transistors in general

4. Boron and arsenic are two of many doping compounds which can be used to create an NPN BJT

5. The 'collector' and 'emitter' pins on a PNP BJT, referenced in the last sentence, are separate pins, and likely never tied together

It should probably redirect to 'Bipolar junction transistor'.

p=positive n=negative

Symbol

Is that symbol correct? Shouldn't it have an arrow indicating a) which is emitter and which is collector, and b) whether it's NPN or PNP? B.Mearns ^*, KSC 02:39, 25 April 2006 (UTC)[reply]

Yeah, someone used an automated tool to replace all the PNG images with an SVG replacement, without checking to see whether the replacement was actually an improvement. In this case, the SVG was broken. — Omegatron 05:01, 25 April 2006 (UTC)[reply]
