DESCRIPTION
Available in high power packages, the
BTW67 /
BTW69
Series is suitable in applications where
power handling and power dissipation are critical,
such as solid state relays, welding equipment,
high power motor control.
Based on a clip assembly technology, they offer a
superior performance in surge current handling
capabilities.
Thanks to their internal ceramic pad, they provide
high voltage insulation (2500V
RMS
), complying
with UL standards (file ref: E81734).

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.
