ZETEX ZLLS400

ZLLS400
40V SILICON HIGH CURRENT LOW LEAKAGE SCHOTTKY DIODE
SUMMARY
Schottky Diode VR = 40V; IF = 0.52A; IR = 10mA
DESCRIPTION
This compact SOD323 packaged Schottky diode offers users an excellent
performance combination comprising high current operation, extremely low
leakage and low forward voltage ensuring suitability for applications requiring
efficient operation at higher temperatures ( above 85⬚C) see Operational Efficiency
chart on page 4.
key benefits:
Performance capability equivalent to much larger packages
Improved circuit efficiency & power levels
PCB area savings

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.
