## **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. 3 of 6 ZLLS500 Document number: DS33227 Rev. 6 - 2 January 2012 © Diodes Incorporated **www.diodes.com** **==> picture [63 x 12] intentionally omitted <==** **----- Start of picture text -----**
