How exactly does CPU set C BE lines on a PCI bus? In the PCI bus spec, when in the address phase of a transaction, there are extra bits for specifying the type of transaction (called C BE) These lines are also re-used during the data phase of the

How do I know if which leg is the emitter or the collector? (Transistor . . . \$\begingroup\$ 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
transistors - BJT high frequency analysis - Electrical Engineering . . . From what I remember, the Cbe depends on the emitter current Higher current causes lower reac (1 gm); at 1mA, its 26 ohms at 2mA its 13 ohms 2mA is 4 volts 2Kohm (ignoring the emitter bypass cap) Thus your circuit has an incremental emitter-base small-signal resistance of about 13 ohms
Simple transistor switching example should show LED off Ensure transistor is CBE bottom to top as per 2N2222 datasheet or find what it really is Identify C B E with certainty Ensure NPN transistor Collector via R3 and LED to V+ Emitter to ground 10K from Base to ground 10K via switch to V+ Like this with different values, but I have added extra 10k from base to ground (a wise precaution)
C-E leakage current, breakdown voltage in 2N2222A 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 \$\endgroup\$ –

Cbe we can find using FT value from the datasheet and this equation \$ \large C_{BE} \approx \frac{1}{2 \pi F_T *r_e}\$ And Cce is usually extremely small and is generally ignored since the input capacitance is so much larger \$\endgroup\$ –
Same transistor type, swapped emitter and collectors? Normal? But there are two different pinouts for the P2N2222A (a CBE pinout) and the PN2222 (EBC pinout ) So at least given my BC547 ignorance it seems at least possible in concept that other devices may have varying pinouts as I already know one example where it happens But I doubt it
