Registration Data Formats (RDFs)

A Registration Data Format (RDF) is a guideline describing how a device manufacturer should present mechanical and electrical data in a uniform and orderly manner such that a device user can readily compare and select the component to meet application requirements. These formats are required to obtain a JEDEC Type Registration designation as they provide the minimum data necessary for the characterization of a particular class of solid state devices upon which a type designation is assigned. For the purpose of achieving standardization, specific registration formats are available to fit particular device types. These formats are subject to change as new semiconductor developments or circuit applications become practicable. For further details refer to JESD282, subclauses 2.7, 2.8, and 2.9.

The RDFs are primarily developed and maintained by the JC-22 Committee and JC-25 Committee.

When preparing a registration data format for submission:

Every item preceded by an “M” is a mandatory item and must be completely filled in, since it represents an essential rating or characteristic required to ensure device interchangeability in intended application. The data requested in other items are optional and should be filled in as appropriate to ensure interchangeability in those special applications in which the device is intended to serve. In any event, the data supplied should adequately define the device in terms of interchangeability in the intended application and should distinguish it from existing registered devices. If additional data are necessary to ensure interchangeability, the data should be submitted as part of the registration. Company data sheets may also be included. There should be no question as to the intention behind, or interpretation of, any parameter or test listed on a RDF.

When outline dimensions of the device are to be given, if possible, an outline drawing registered with JEDEC should be used. Registered outlines are found in the latest edition of JEP95, JEDEC Registered and Standard Outlines for Semiconductor Devices. If such a registered outline is not applicable, an outline drawing must be furnished on a separate page attached to the format.

Delete all italicized notes, all unused items and all “M's”. Renumber the items in proper sequence wherever necessary to avoid gaps in the item numbers used.

All data submitted for registration, whether mandatory, optional, or supplemental to the format, becomes a part of the formal registration.

All JEDEC registered data must appear on the device manufacturer's commercial data sheets and be identified as JEDEC registration data by means of asterisks. Additional data, including performance curves, may be included in commercial data sheets provided interchangeability is not affected. JEDEC does not require companies to disclose Essential Patents or provide RAND1 assurances when preparing a registration data format for submission. However, companies may do so voluntarily in order to assist future users of the resulting data sheet.

Once completed, to apply for JEDEC Type Registration, submit to: JEDEC Type Administrator, Phileasher Tanner, 703-907-7540.
