Abstract
A voltage-controlled switching device includes a drain/drift structure formed in a semiconductor portion with a lateral cross-sectional area A, a source/emitter terminal, and an emitter channel region between the drain/drift structure and the source/emitter terminal. A resistive path electrically connects the source/emitter terminal and the emitter channel region. The resistive path has an electrical resistance of at least 0.1 mΩ*cm/A.
