STPS1L40
Low drop power Schottky rectifier
Datasheet - production data
Features
Very small conduction losses
Negligible switching losses
Low forward voltage drop
Surface mount miniature packages
Avalanche capability specified
Description
Single chip Schottky rectifiers suited to switched
mode power supplies and high frequency DC to
DC converters.
Packaged in SMA, SMB and SOD123Flat, this
device is especially intended for surface
mounting and used in low voltage, high frequency
inverters, free-wheeling and polarity protection
applications.
