Schottky Diodes
Schottky Rectifier Diodes
The ZHCS Series diodes provide excellent high performance specifications in miniature surface mount packages. An
optimized geometry / process with superior packaging gives an unmatched IF / VF performance and PD capability, enabling
significant space savings, circuit efficiencies and cost effective solutions to larger package options.
Complementing the very low VF performance of the ZHCS series Zetex has introduced 4 new surface mount, high current,
very low leakage, fast switching Schottky diodes. These new low leakage diodes are ideally suited to applications requiring
efficient operation at higher temperatures, often a significant limitation of conventional Schottky types. The ZLLS series
diodes are provided in a choice of packages which relate directly to die size and IF performance ensuring that designers have
the optimum choice of package size / performance / cost.
