This standard is applicable to diodes that are used as voltage regulators and voltage references. It describes terms and definitions and explains methods for verifying device ratings and measuring device characteristics.

Voltage regulator diodes are sometimes used as transient voltage suppressors, but are not characterized for their clamping ability or peak pulse power rating. Terms and tests related to transient voltage suppression will not be covered in this document, but are discussed in the JEDEC document JESD210 on Avalanche Breakdown Diode (ABD) Transient Voltage Suppressors.
