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 VF ZHCS series diodes.
