I'm super new to electronics and am still trying to wrap my head around how to read a datasheet. I've attached an image of a part of this datasheet that I'm trying to figure out:
https://www.fairchildsemi.com/datasheetsÂ/2n/2n3906.pdf
If I understand correctly (and someone please tell me if I am correct or incorrect, I am only interested in transistors as switching devices even though I know they can be used as amplifiers) this PNP transistor requires 1mA on the base pin when there's 10mA on the collector pin (regardless of Voltage since Current is what determines if the transistor is saturated or cut-off, which also means there's a 10:1 ratio between collector and base) and that the .85V is the voltage drop of the transistor... Someone has been trying to explain this to me on a different forum and this is what I've come up with so far.
