- How do I know if which leg is the emitter or the collector? (Transistor . . .
Off the cuff - for jellybean transistors I almost invariably use BC337 (NPN) and BC327 (PNP) - both CBE A transistor selector book woul;d be the easy way to check distributions as they have pinout tables which they assign a letter code to and then show the relevant code for each device
- How are C (OBO) and C (IBO) defined? - Electrical Engineering Stack . . .
I'm thinking that in an ordinary grounded emitter setup, where one rather wants to know cbe and cbc, one could approximate it to Cbe = Cibo C b e = C i b o and Cbc = Cobo C b c = C o b o At least that's my reasoning for it to make any sense

I have a little bit of confusion on how the textbook author is determining the high frequency cutoffs for the parasitic capacitance parameters for a common emitter amplifier This is Boylestad Elec
- Simple transistor switching example should show LED off
I checkd 2N2222 data sheets from several manufacturers ALL I found including metal can ones show transistor is CBE readingUP the breadboard as shown (terminals 48-49-50) SO there is NO DOUBT that they have the circuit VERY WRONG as shown Their C (terminal 48 ( goes via R3 to B- (ground) For an NPN transistor it should be B+ +12v etc Build the circuit as I have suggested It will work
- C-E leakage current, breakdown voltage in 2N2222A
The device I'm testing is labeled PN2222A However, I'm using the pinout as shown in the ON Semi datasheet, which is CBE Testing with meter as you suggest is consistent with this pinout When used in a 5V circuit (ie, 5V at B to switch 5V across C-E), it works as expected, leading me to believe I have the right pinout

Below is an NPN transistor characteristics for Vbe versus Ic at different Vcb or Vce: It seems like in the active region, Vbe vs Ic curves gets steeper with an increasing Vce The following equat
- amplifier - (Lack of) Miller Effect in Cascode considering Common . . .
I'm currently working on an analysis of a standard Cascode circuit, in particular why the frequency response is so good as it reduces the miller effect I have had a very vague explanation given t
- Simple circuit works with BC547, but not with 2N3904
The transistors can be used interchangeably and exchanged, yes, but they don't have the same pinout BC547 has CBE and 2N3904 has EBC
