FEATURES AND BENEFITS
The Bridges series from ST Microelectronics has
been designed to allow a better standardization of
packages on boards principally designed with ISO-
TOP packages. The insulated package of the
bridge will be able to sit on heatsink with other
components. Single phase and 3-phase high
power SMPS, UPS, MOTOR DRIVES and WELD-
ING equipment will primarily find advantage in
these industry package products.
