Available in non insulated TOP3 high power
package, the BTW69-1200N is suitable for
applications where power switching and power
dissipation are critical, such as by-pass switch,
controlled AC rectifier bridge, in solid state relay,
battery charger, uninterruptible power supply,
welding equipment and motor driver applications.
Based on a clip assembly technology, the
BTW69-1200N offers a superior performance in
surge current handling and thermal cooling
capabilities.
