I noticed that since renesas overtook nec some references have changed. I'm
searching for the 2SD2403 which can be with GX, GY, or GZ marking on the chip
but nowadays I'm mostly finding 2SD2403-AZ, 2SD2403T1-AZ, and 2SD2403T2-AZ. And
when downloading the datasheet on renesas website I always get a copy of the
nec datasheet with an added disclaimer preface from renesas. But there are no
reference to the new ref. code. So if someone knows more about this?


Hello,

I don't really know NEC numbering, but could the new suffix's indicate
a different package, like surface mount instead of through hole? The
GX,GY or GZ rating is a beta range on the transistor. See:

http://pdf1.alldatasheet.com/datashe...C/2SD2403.html

on page 2 of the PDF.

Also, sometimes the suffix can tell how things are shipped or packaged,
like on a tape reel for auto insertion, or loose, or in a tube.

Tim
