Abstract

A two-stage protection device for an electronic component protects against transient disturbances. The electronic component may be a semiconductor component, and may include one or multiple transistors and/or an integrated circuit. The protection device is connected to at least a first contact and a second contact of the electronic component, and is disposed essentially in parallel to the component that is to be protected, between the first contact and the second contact. The protection device includes a first stage with at least one diode and a second stage separated from the first stage by a resistor. The second stage includes at least one diode arrangement having two back-to-back disposed diodes which are disposed cathode-to-cathode.
