SK12A THRU SK120A
1A Surface Mount Schottky Barrier Rectifiers
■ Features
• Electrostatic discharge (ESD) test under IEC6100-4-2 standard >16ΚV(SK12A~SK16A). standard >10ΚV(SK110A~SK120A).
• Low profile surface mounted application in order to optimize board space.
• Low power loss, high efficiency. • High current capability, low forward voltage drop. • Ultra high-speed switching. • Silicon epitaxial planar chip, metal silicon junction. • Suffix "G" indicates Halogen-free part, ex.SK12AG. • Lead-free parts meet environmental standards of
MIL-STD-19500 /228
■ Mechanical data
• Epoxy:UL94-V0 rated flame retardant • Case : Molded plastic, DO-214AC / SMA • Terminals : Solder plated, solderable per
MIL-STD-750, Method 2026 • Polarity : Indicated by cathode band • Weight : 0.002 ounce, 0.055 gram
