Abstract
A power transistor module including a power transistor with a first common power node, and a split control node. A first clip is connected to a portion of a second power node so that current through a first control segment of the control node is directed through a first transistor portion and through the first clip. A second clip is connected to another portion of the second power node so that current through a second control segment is directed through a second transistor portion and through the second clip. A ratio of an area of the first transistor portion to a combined area of the first and second portions is 5 percent to 75 percent. A shunt is coupled in series to the first clip. The shunt may be directly electrically connected to the first portion of the power transistor.
