Eagle PCB Layout Editor PNP Transistor E and C pins swapped?

Question

Device -> BC557B-PNP-TO92-EBC (*-PNP-)

Package -> TO92-EBC

Library -> transistor

Are the E and C pins swapped somehow when you design the board?

The orientation of the transistor (silkscreen) on the board doesn't comply to datasheets of the above mentioned device.

I'm looking in Eagle 7.5 There are many transistors in the transistor libraries using the package TO92-EBC that are incorrect. There is also the following package with an incorrect name Library = transistor-pnp.lbr Package = TO92-EBC.pac The pads are actually CBE Perhaps Cadsoft will assign someone to clean up all the transistor libraries.

AFAIK there are only 2 versions of TO92 were pads are in a row or are in a triangle and all of them are numbered 1,2,3 and that is it. Cadsoft should really clean this mess up. For H.J. Windt I suggest to open your own library copy the devices into it and rename the pads correctly according the data sheet. -- Mit freundlichen Grüßen / With best regards Joern Paschedag
