Semiconductor appliance e.g. as switching device for motor control in vehicle air-conditioning system, has first and second main current electrodes arranged opposite one another

摘要

The semiconductor appliance has design modifications for solving the problem of the length of, and unequal length of the current paths, a problem that becomes more acute with the increasing number of semiconductor devices (chips) (24) mounted on the substrate (22,23). A first main current electrode (27) is connected in common with each of a number of semiconductor devices (chips) via the substrate, and a second main current electrode (25) is mounted opposite the first main current electrode and is connected in common with each of the number of semiconductor devices (chips).
