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 V F ZHCS series diodes.
