Chip Schottky Barrier Rectifier
FM540S-AL
5.0A Surface Mount Schottky Barrier
Rectifiers 40V
Features
Batch process design, excellent power dissipation offers
better reverse leakage current and thermal resistance.
Low profile surface mounted application in order to
optimize board space.
High current capability, low forward voltage drop.
Guardring for overvoltage protection.
Ultra high-speed switching.
Silicon epitaxial planar chip, metal silicon junction.
Lead-free parts meet environmental standards of
MIL-STD-19500 /228
Suffix "-H" indicates Halogen free parts
