Short duration pulse test used to minimize self-heating effect. The Zener impedances (ZZT, ZZK) are measured by superimposing a minute alternating current on the regulated current (IZ). No purposefully added lead. Halogen and Antimony Free. Product manufactured with Data Code V9 (week 33, 2008) and newer are built with Green Molding Compound. Product manufactured prior to Date Code V9 are built with Non-Green Molding Compound and may contain Halogens or Sb2O3 Fire Retardants.
