Features
-Halogen free.
-
Batch process design, excellent powe
dissipation offers better reverse leakage
current and thermal resistance.
-Low profile surface mounted application
in order to optimize board space.
-Tiny plastic SMD package.
-Low power loss, high efficiency.
-High current capability, low forward voltage dorp.
-High surge capability.
-Guardring for overvoltage protection.
-Ultra high-speed switching.
-Silicon epitaxial planarchip, metal silicon junction.
-Lead-free parts meet environmental
standards of MIL-STD-19500 /228
