An early 1950s transistor using the precursor to the EIA/JEDEC part numbering system

In the fall of 1999, JEDEC became a separate trade association under the current name, but maintained an EIA alliance.

This early work was followed by a number of test methods, JESD22, and product standards. For example, the ESD caution symbol, which is the hand with the line drawn through it, was published by JEDEC and is used worldwide. JEDEC also has a dictionary of semiconductor terms. All of JEDEC standards are free on the Web for downloading after a free registration.
