Description
Available in a high power insulated package, the
BTW68 series is suitable for applications where
power handling and power dissipation are critical
such as solid state relays, welding equipment and
high power motor control.
Based on a clip assembly technology, this device
offers a superior performance in surge current
handling capabilities.
Thanks to the internal ceramic pad, the device
provides high voltage insulation (2500 V
RMS)
and
complies with UL standards (file ref: E81734).
