Semiconductor device and semiconductor module

摘要

A semiconductor device is provided formed as an inverter, control circuits (31 - 33) have terminals connected to floating source pins (VS) which are limited to output terminals (U, V, W). In order to hold voltages across floating source pins (VD, VS), capacitive elements (51 - 53) provided in the device (101) are connected to the output terminals (U, V, W). Thus, the terminals which are connected with the floating source pins (VS) are shared by the output terminals (U, V, W), whereby the number of the terminals and wiring patterns are reduced.
