Zusammenfassung:The invention relates to an electronic device (200) for protection against transient voltages in high-power applications. The electronic device (200) comprises: i) a semiconductor substrate (220) comprising an active element (Dd) having at least two terminals (T1, T2); ii) a conductive pad (225) provided on said substrate (220) and being electrically coupled to one of said terminals (T1, T2); iii) electrically-conductive solder material (226) provided on the conductive pad (225); iv) a first conductive part (230) electrically coupled to the conductive pad (225) via the electrically-conductive interconnect material (226). The electronic device further comprises a wall (229) being provided along the periphery of the conductive pad (225) for forming a lateral confinement of the interconnect material (226) on the conductive pad (225). The invention further relates to a method of manufacturing such electronic device. The proposed invention offers a solution for two problems: a) limited interconnect coverage when using lead-solder (due to the solder limitation), and b) the limitations when using lead-free materials (due to the government restrictions).
