Description
Dual center tap Schottky rectifier suited for high
frequency Switch Mode Power Supply.
Order code
Packaged in TO-220AB and I2PAK, this device is
intended to be used in notebook and LCD
adaptors, desktop SMPS, providing in these
applications a margin between the remaining
voltages applied on the diode and the voltage
capability of the diode.

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.
