Hello All,
This along the lines of my previous 'High Side MOSFET' switch post yesterday but in relation to transistors.
In some situations I'd like to use a PNP as a high side switch. I see that some PNPs are -V & -I, and some are +V & +I. Visually, with the base to the left, emitter up, and collector down... what is considered
+I vs. -I? I would assume E--->C is considered positive flow?Also, that leads to datasheet data such as Vceo (collector emitter voltage) of 40V. I assume the max V present at the collector is Ve +
40V? Or... Vceo of -40 is emitter can be Vc + 40?Thanks,
John
