Operational Efficiency chart
The operational efficiency chart indicates the beneficial use of the ZLLS Series diodes in applications requiring
higher voltage, higher temperature operation. Circuits requiring Low voltage Low temperature operation will
benefit from using Zetex low VFZHCS Series diodes.
