Ok, pull out JEDEC Publication 95 Book three. Everybody with me and have their copy handy ;)
The following part matches the JEDEC specification for MO-178 which is a version of SOT23-5 http://cache.national.com/ds/LP/LP3985.pdf I prefer the JEDEC-95 specification for packages because.... components which reference them have the correct dimensions and pin numbering. The JEDEC standard JEP-95 may be viewed on line at www.jedec.org To reach the JEP-95 pdf files you need to register for free. I am curious to know which SOT23-5 packages differ from the MO-178 standard. Can some one post an example.
