STPS2060C
High voltage power Schottky rectifier
Main product characteristics
Description
High voltage dual Schottky rectifier suited for
switch mode power supplies and other power
converters.
Packaged in TO-220, this device is intended for
use in medium voltage operation, and particularly,
in high frequency circuitries where low switching
losses and low noise are required.

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.
