Operational Efficiency Chart
The operational efficiency chart indicates the beneficial use of the ZLLS series diodes in applications requiring higher voltage and higher
temperature operation. Circuits requiring low voltage, low temperature operation will benefit from using Diodes’ low VF ZHCS series.
