April 2010 Doc ID 15521 Rev 2 1/11
STPS20M100SPower Schottky rectifier
Features High current capability Avalanche rated Low forward voltage drop current High frequency operation Insulated package: Insulation voltage 2000 V rms Package capacitance = 12 pF
DescriptionThis single Schottky rectifier is suited for high
frequency switch mode power supply.
Packaged in TO-220AB, TO-220FPAB, D2 PAK
and I2 PAK, this device is intended to be used in
notebook, game station and desktop adaptors,
providing in these applications a good efficiency
at both low and high load.
