Today at my bench, my boss wanted me to look at a simple inverter for a panel touch screen LCD monitor. While collecting information I found that the ID codes on the smt did not match what usually go by.
For example I had a "2A (underscore V) 3D" on a sot23 transistor. The chart tells me it is a 3906 (pnp) transistor however, I found that it is actually closer to being a fet transistor.
Then I looked a the power transistors to the primary side of the inverter transformer, they were NPN types however, the "DK" Id on them point to a chart indication they are PNP and slightly incorrect package match.
Does a list exist that better matches these?
