Reduced oscillation power switching module and method for producing a power switching module circuit

摘要

A power switching module contains a power semiconductor component (101a, 101b) with three connections, which is designed for a nominal current, and a freewheeling unit (108a, 108b). The freewheeling unit (108a, 108b) contains a pn diode (103a, 103b), which is integrated in a first semiconductor material with a first band gap, and a Schottky diode (104a, 104b), which is integrated in a second semiconductor material a second band gap that is larger than the first band gap. The Schottky diode (104a, 104b) is electrically connected in parallel with the pn diode (103a, 103b).
