Assignee: INFINEON TECHNOLOGIES BIPOLAR GMBH & CO. KG
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 17:
18. A method for voltage limiting by the power semiconductor component of claim 1, the method comprising:
applying an electrical voltage to the front-side electrode and the rear-side electrode;
activating the breakdown structure of the second type owing to a voltage change of the voltage present at the front-side electrode and rear-side electrode that is greater than the predetermined voltage gradient and/or activating the breakdown structure of the first type owing to a high voltage present between the front-side electrode and the rear-side electrode that is greater than the predetermined voltage level;
clamping the voltage present between the front-side electrode and the rear-side electrode to the predetermined voltage level of the breakdown structure of the first type during an activation period of the triggering structures; and
fully switching on the switch-on structure after the activation period has elapsed and reducing the voltage present between the front-side electrode and the rear-side electrode.
