Features and benefits
■ Very low profile package: 0.85 mm
Description
■ Backward compatible with standard STmite
Single Schottky rectifier suited for switch mode
power supplies and high frequency DC to DC
converters.
footprint
■ Very small conduction losses
■ Negligible switching losses
■ Extremely fast switching
Packaged in STmite flat, this device is intended
for use in low voltage, high frequency inverters,
free wheeling and polarity protection applications.
Due to the very small size of the package this
device fits battery powered equipment (cellular,
notebook, PDA’s, printers) as well as chargers
and PCMCIA cards.
■ Low forward voltage drop for higher efficiency
and extended battery life
■ Low thermal resistance
■ Avalanche capability specified

In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a Lead-free second level interconnect. The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com.
